Hi all!

New corvette owner here, I recently bought a 2008 Base 1LT auto and long story short....i got taken. Nobody's fault aside my own and now im tasked with fixing all these small issues that seem to never stop popping up.

I was wondering if any of you could point me in the right direction for some of the issues listed below, I do all my own work as i take it all as a learning experience and would be the best financial move for me. Thank you in advance!

Drivers door;
Issue 1 - Window doesn't always index, I'd say 7/10 times it will not index unless i attempt to open and close the door several dozen times.
Issue 2 - Recently the door buttons started not responding from either side and I'm forced to use the release latch on the floor or in the trunk to open it. (Most commonly when it rains or been washed....maybe a electrical short)
Issue 3 - Window seems to be not tight against the seals when closed and creates a wind rushing in noise at thruway speeds. (60+mph)

Engine;
Issue 1 - When at operating temp a internal tick is heard that follows rpm and can be heard over the exhaust.
Issue 2 - A what I'll call hiccup to the idle, can be felt and audibly heard. I recorded it with my scan tool and can be visibly seen on the graph. (on a otherwise perfectly straight line RPM graph there's dips in the RPM when this hiccup is heard/felt)
Issue 3 - Throttle has no consistency - pressed 0-10% will see small RPM gains but then 10-15% will see the car fall back to idle then 15-25% will see the RPM skyrocket back to where you'd expect it to be and so on.

Transmission;
Issue 1 - First to Second shift is Rough/Jerky. (Best description i have is that 1st gear seems way over-fueled and then it falls on its face when going into 2nd and then it feels severely under fueled until 3rd)

Body;
Issue 1 - Front bumper wont stay clipped down where it meets the fender/headlight
Issue 2 - Rear view mirror destroyed, Cannot find a 08 replacement - only early c6 styles

My car;
2008
74k Miles
Seven...yes SEVEN prior owners
Automatic
Flow-Master Cat back Exhuast
Unknown on tuning

 

Sorry you’re having so many issues. Couldn’t things I would suggest:
1. Replace all fluids
2. replace battery
3. Clean door pad contacts
4. New clips for the bumper issue (box of 10 for $15 on Amazon)
5. Review mirror https://www.chevynationparts.net/v-2...***-windshield

 

1 by 1 you'll get it all sorted out. And yes replace all fluids including gear oil. You'll be suprised how smooth it is. Definitely get those clips for your bumper gap. Mine did this and I get it fixed. If your doors wont open after a new battery I suggest new door latches.
if windows wont fix I suggest new motors. Engine ticking... hmm? New oil... spark plugs and wires. Use some lucas (just once) to clean of the injectors, fuel lines and what not.
Possibly get a tune to fix throttle or maybe a new sensor

 

The ticking sound sounds like classic exhaust leak or header leak. The first to second gear shift when engine is cold is a little rough. Clean the door pads change the battery and re-index the windows , change all fluids, check all plug wires at both ends. Have the upper intake and injectors cleaned.

 

Agreed, sounds like you bought car with 74k miles and some little issues have developed over the years. Let me guess, the price was too good to pass up?

Either way, nothing in your list is that concerning, unless you don't have the ability to work on cars yourself and stretched your budget already.

 

Thank you all for your directions, ill begin collecting all the items ill need for this!

I guess my problem really is I'm just flustered that i have yet to be able to enjoy this new investment of mine due to issues that are small but take away from the driving experience for me that just never seem to stop popping up. I have the ability and tools to do all the work myself that can be preformed without the use of a car lift and i have the budget to take it to a dealership as a last resort but i already made one financial mistake by being a dumb dumb when i looked over and test drove the car and did not catch nor notice most of these flaws that where present during that time.

As for the price.... Yeah there's a clear reason now why it was the cheapest 08 base auto in a 500mile radius of me when i was looking for one.

To clarify a little on what i mean by things just seem to keep popping up, heres what i already fixed that i didn't list as a current issue.

Alternator
Idler pulleys
Tensioners
Belts
Harmonic Balancer - Made dealer fix it before i bought it
Tank B Sending unit - Made dealer fix it before i bought it
Starter button

Small story - feel free to ignore;
No joke, i literally managed to make it to my house on day 1 and then the horrendous belt squeal began which prevented me from driving the car, simply cause its embarrassing being that guy with the super loud squeal (that's not from a supercharger) from his car that people are already looking at. So i parked it ordered all new oem Belts/Idlers/tensioners and the noise went away for like a day then it came back but very metallic sounding so i listened around with a scope and found it to be the alternator bearing, changed that and its been silent since. Now the next time i got to drive it i finally started focusing on noises other than that awesome LS3 and realized my drivers window, while it appears to be fully up is allowing air rush in and sound like its own A/C on full blast. Move onto the 4th time i got to drive it and the rear view mirror just FALLS OFF. Come to find out that the dealership or prior owner just used this black goop to hold the mirror to its ball socket since that ring piece was broken.

Since then my car has been in my driveway and Ive made it my mission to make it 100% before i start driving it again. I want to be able to enjoy this car and not be constantly reminded i bought a cheap, seven owner used car that i was a dumb dumb for buying. (this particular one. I hold none of these problems towards corvette itself)

 

OP...I (we, the CF) see these types of post all the time. Perhaps if you listed your location in your bio, someone nearby might offer to lend a hand. Good luck getting everything sorted out...jmho.

 

Thank you for the tip! I took the time to fill out my bio/profile.

 

You might have a new belt and the squeak stopped...but if it comes back it is probably because you do not have a continental gator back belt installed. I bought pulleys and belts to stop my squeak. Even tried bar soap and belt lubes and countless of thins. Nothing ever worked.

Then I bought a continental gator back belt like everyone here recommends... it worked. Been over a year now and no squeek

 

That tends to be the case when you go cheap. Good news is you have the ability to fix stuff, otherwise you would end up with the most expensive cheapest car if you had someone else getting paid to fix it, haha.

 

Hi all! Good news and update,

I've fixed all my listed issues aside for just one!

You've been all really helpful and I'm grateful for that!

My only issue left is my 1st gear to 2nd gear shift. some times 1st seems to have all the power/pull in the world but then it hits second hard and falls on its face and a then acts like it has no power at all until 3rd. this is a completely random occurrence and a very odd one, i know it'll happen before it begins as my throttle sensitivity will be through the roof on take off for some reason.

My theory (a novice one at that) is that its my throttle response instead of my transmission, I feel as if these moments my throttle curve is all wonky and over responsive but when it hits 2nd gear it drops back down to represent the very little amount of throttle im actually giving it. Is realistic theory?

*Automatic transmission for the new readers

 

Are you getting any fault codes? Have plugged in a code read. If your throttle response is wonky, it may be the throttle position sensor is bad, or a broken wire, or not making a good connection at the connector. Check to see if you have a throttle controller hooked up above your gas pedal. Those can go bad and do all kinds of weird things.

Good luck

 

 

Turn off the traction control and see if it does the same thing.Seem's like it might just be pulling timing,cutting fuel and doing what it's designed to do when car spins on shift and they will take a few seconds to recover from that.

 

A majority of the issues you've listed are electrical in nature. Where did the car come from? Is it a flood car from somewhere or reconstructed title?

 

Pull the MAF sensor and clean it with Maf cleaner. The Maf sensor not only reads the amount of air flow, but has the air temp sensor in it as well.
Also, when you have your Maf in hand, check it to see if it one of the know defective units.

To add here, if the car has had a tune, tune may be all jacked up and causing the problems alone. Also if running an after market air filter system, some of them have been known to cause MAF flow reading problems, and you have to go into the tune to resolve those problems. Hell, just some filters like the K&N that require oiling, can be over oilled to cause the maf To be come dirty fast, and takes you back to step one of just cleaning the Maf sensor to begin with.

So to clean the Maf, Maf cleaner sprayed through the right hand side small window to clean the internal parts in the sensor,


Also, tune off Traction control, and see if that helps. Hence if not an Maf sensor air flow reading problems, could be that the rear end is breaking free in on the shift to second, and TC kicking in for that gear instead.

 

No fault codes sadly. and nothing seems aftermarket above my throttle pedal.

I would assume the same but this happens when i give the smallest amount of throttle. 7/10 times itd crawl from a take off but 3/10 times itll randomly act like im giving it wayyyy to much throttle. Ill give a update though when i drive a few times with traction control off to see if it ever happens then.

Clean Car fax, Same for the title. I cannot seem to find anything that would indicate a flood or accident.

I actually had this same thought so when i did my tune up i put a brand new OEM MAF in. Which seem to help some of my other issues. or at least seemed that way.




I Think what ill do now is spend a couple days driving with TC off and see if this issue continues.
