Default 2 things

First, I bought this foam "engine clean" from advanced auto store normally like 3 bucks on sale for 1.40....Bouught cuz my car had tranny trouble before a couple motnhss ago and fluid spewed oil leaks and apparently its never had a good undercarrriage wash. Shot this stuff all under the hood and underneat the car. The water was pure black. Hopefully this will make it stop smoking....Hopefully. Also cleaned out the throttble body AGAIN and it was sooo gunked up. I think that might be part of the idle problem but I am in there tryng to figure out whats going on. Havent got it off yet but I am workn on it. Thanks to the people who helped me in the right direction especially CFI-EFI and RRT vette.

2nd, I was out there cleaning the underhood and these jerks in a diesel truck, saw me down the road apparently and slowed down right in front of my driveway and revved the **** out of it and black smoke was everywhere. They kept saying stupid stuff like "lets race the ****box, and daddys bratt so I gave them the bird and a few well chosen words and they kept threatening and cussing and carrying on so I eventually ignored them cuz traffic was coming up behind them and they had to move. Yep the ****box is getting worked on....I dont know if my vette has the power to compete with that diesel. Big V8 and god knows what mods. Sounded beastly...20 yr old guys in the jacked up thing probably trying to show off. I wouldve loved to smoke there @ss at a stoplight. Maybe one day soon.... Thought id share my experience with the lower class of the world. Thanks.

I found it amusing. Mainly I was reccomending the product though. Very good stuff for a cheap price. I like cheap...

Jay, make sure you take the IAC out of the TB when you clean it. There could be you throttle problem. Clean the IAC and the IAC air passage. When you reinstall it make sure the gasket is in good shape or get some gasket paper and make one to replace the old one. Make sure the tip of the IAC is no further than 1 1/8" from the flange when reinstalling it. Could cause damage otherwise. You might have to reset the minimal idle after you put the TB back on. There are steps to follow in doing this. After cleaning all the leaking fluid away, this will show you where the leak(s) is coming from.

The dude in the truck is jealous and/or lacking cahounas, otherwise he wouldn't have messed with you unless you provoked him.

I been wondering where u been havent seen ya in a while. Today, I cleaned out the "inside of the butterflys. I took off the top section with those hexagonal bolts got down in there and got the front ones off.....I cant get the thorttle body off? I need help. Can you give me the location of the bolts or what im doing wrong also. Once I get it off I need you to tell me where everything is and what I need to buy to fix this problem. It may not seem like a big deal to some of you guys but idling at 1200 RPMs is killing the gas and my brakes are wearing out twice as fast. Im using the 25.00 dollar duralast brakes.

Me provoke? Nope. Im nice unless you start stuff. I thought you of all people wouldve realized im nice. Those who help me, will get generosity in the future.

Hello,


Dont worry about the jerks. One time a truck splashed muddy water on my car out of spite.

BTW keep the racing on the track. Its safer.

Yeah, just kidding with you.

There are 4 bolts that hold the TB on the plenum. They are 10mm. Going from memory, take the air duct with MAF off the TB. Take the cruise control cable, accelerator cable, and TV cable loose from the linkage. There are small clips that hold them on and use a small flathead screwdriver to pry them off and don't drop them (easily lost). Remove the EECS vac line and coolant line from the right side of the TB. Some coolant will come out so have a rag handy.

Disconnect the IAC connector from the right side. Disconnect the TPS and becareful not to move this sensor any. If you plan on setting minimal idle it won't hurt because you will be adjusting it anyway. Then remove the 4 bolts holding the TB down. After there out, just pull the TB off. You may need a new TB gasket before installing the TB back on ($4 at a parts store).

After the TB is off unscrew the IAC. Use a old toothbrush and TB cleaner on everything dirty. A new IAC is $35 and it comes with a new gasket. If you do get a new IAC take the old one with you because they make three different types. For the high idle I would say either dirty/lazy IAC, TPS out of adjustment, dirty MAF, or vac leak.

Let me know if you have any other questions.

Who cares? A fast truck..why? You could strap a 700hp crate motor in a beat up station wagon and it would be fast...so what. Trucks were made for work and haulin' things. To each there own I guess.

It's called a sleeper and everyone with a vette thinks they are the king, but to get embarrassed by a truck, I just laugh. I've embarassed a few in my truck.

IMHO drag racing is you against the clock and yourself. Are you REALLY competeing with that truck? Or anyone else for that matter? You are always trying to beat YOUR best time based on the mods you have and such. I respect speed but not all fast vehicles are cool. Mojo, lets see that truck "humble" you autocrossing. Vettes are really more than drag racers aren't they. That being said..that's a damn fast truck...and truck is what it will always be.
I apologise for the hijacking of this thread. Thanks for the tip on the Engine Clean.

OK, but let's do it on dirt, or in snow, and we'll haul some crap in the back.
Bracket Racing is against the clock, with heads up, it's first to the finish line, well bracket racing is also first to the finish line.

When it comes down to competition, first to cross the finish line usually wins.

You're right, that truck wouldn't do crap on a road course or autocross, and as you said, not all fast cars are cool, but the fact that they can whoop you in an apsect you are more than likely to encounter, it still gets my vote.
How about a low 10 second Civic that looks like crap? Beat me in a drag race, and quite possibly has the potential in an autocross as well. It's an ugly car, but performs well. When it comes to racing, it's function, then form.
