Did you know that you need to fill it and then start the engine and refill it till it while the engine is running until it wont take any more????

If you just fill it till it wont take any more fluid,, thats your issue. When you removed the plug to drain it, it should have gushed out. If you remove the plug and it doesn't gush out, it way too low.

That makes me suspect the MAF again.

 

ok sounds good ill check it 2mro and get back to you guys...but what is the complete procedure bill curlee?

 

ok i think i went wrong somewhere...The car was full operating temp instead of being between the 2 temperatures its need to be at when filled and i did not fill with car off then start and refill... what is the procedure so i can check it 2mro morning? but can you put it in simple terms instead of the service manual terms lol.

oh and BTW i do have the service manual for my car i just could not find the page to service the A4 tranny all i could find is the manual tranny servicing? can you point me in the right direction?

hmmm i clean that sucker seriously every couple months along with cleaning my black wing...maybe the MAF is just bad? ill re clean the MAF and check the tranny fluid 2mro morning..

thank you all for the help

 

u probably damaged ur MAF when cleaning it...... i did that on my mustang.. if ur gas mileage went down its more than likely ur maf.....

do u have any codes in dic??

and dont clena that sucker (MAF) every few monts or so like u said..... u dont need to... once every few years or so is fine lol

u should be able to get a used Maf here for 100 bucks...i would do that first... if its not your MAF u can always resell here on the forum

 

ok im almost positive it is the tranny low on fluid i know i did it wrong and it started acting up right after that. when i get off the gas it slows down waaay faster than it used to...im going to go have lunch then im going to check the fluid and ill get back to you guys... if its not that then ill change out the MAF....but wouldnt i have a code saying the MAF is acting up?

 

UPDATE!!!!

Hey guys just got my car from the shop after putting in a fully built tranny, new torque converter, and a 3 rib 3.42 diff...the car still does the tugging/ pulling when on decel and the engine rpms still bounce around when put in neutral...i am still getting crappy gas mileage as well...what could it be? should i change out the MAF?

Heres my opinion for what its worth. You most likely not going to put your finger on the issue easily. It going to require some troubleshooting and reasoning skills. To see what the PCM is doing, your going to need to Data Log and look at things like Long Term Fuel Trims (LTFT), O2 Sensor voltages and responses and other sensor data.

To do this, you need to find someone with EFI Live or HP Tuners. Data Logging does not require a license or credits. You just need to find someone who has it and is willing to data log and go over the data with you to see where the issues are.

See if your LTFT are really positive or negative. They should be close to zero or slightly negative. Your O2 sensor voltages should switch from high to low as the car idles. The low millivolt signal will be around 200mv and the high will be around 800mv.

Thats a place to start.

ok ill try to find someone...thank you bill

 

I saw this on another vehicle of mine, it was the idle air control valve. While I was in the area I cleaned the throttle position sensor too. But I'm not very familiar with my LS1 engine yet as I've only had my C5 for 2 months now. Something to think about? Good luck.

The LS series engine does not have an Idle Control Valve (IAC) as the Power Control Module (PCM) varies the position of the throttle blade form fully closed closed to slightly open to control idle. Idle is determined by the PCM thru engine RPM and air flow thru the MAF.

Idle quality is very often adversely effected by things like a Vacuum leak, Dirty MAF, Dirty Throttle blade, defective Throttle Position Switch. Bad O2 Sensors can sometimes also effect idle.

Memphis_vette has reported that he has cleaned/checked or inspected all of this. Its time to start taking a detailed look at the ROOT cause of the issue and begin looking for component responses of a normal idling engine and see here his is breaking down. To do this we use data logging software to tap into PCM and examine what its doing or being told to do.
All of the engine components are going to show this surge in idle. We just have to figure out which one is the cause and which one are reacting.

Another way of troubleshooting is throwing parts at the problem. Thats easy but very expensive and people like to start at the expensive parts first. When I fix a problem, I always prove a part bad before I replace it. Sometimes, the part can be DISASSEMBLED and repaired and reused even though GM didn't intend for it to be repaired. A good example of this is what I found during an electrical issue on a forum members car. The Ignition switch was causing a serious voltage drop and out putting around 6 VDC vs the normal battery output. This is the repair that I found was possible vs ignition switch replacement with a NEW part See link below:

There are a LOT more free repairs that have been submitted by forum members.

Cleaning is FREE, the NEW Switch is about $70-$80

Hey man

I'll send you a PM tomorrow afternoon...I've got a buddy here in town that I'm pretty sure still has HP tuners. I'm sure he'd be down to help out for not much if anything.

Donnie

 

ok sounds good donny thank you

 

Hey man,

I called him last friday(he didn't get back so I called him again a few days ago and got a hold of him)..I was waiting for him to send me a text message with his email address so he could check out this thread.

Deal is he has HP tuners and one of those snapon solus scanners. Cody is the guy you want to talk to at Redding Radiator and Muffler. tell him you're the guy Donnie was talking about with the vette and the LTFT issues...
