Clean throttle body
Where can I find a article on how to clean my throttle body. I have done a search on the Forum and on the Techinfo and couldn't find anything.

It'* not in Techinfo....but will be soon. Part of the problem is the differences in disassembly between the different engines we have here.
1. Remove the MAF sensor (store it in a safe place). Clean it gently with Qtips and rubbing alcohol.
2. Disconnect the IAC and TPS connectors.
3. Disconnect the cruise and throttle cables. Continue removing the TB from the car.
4. Remove the TPS so you don't get gunk on it. Remove the IAC. Remove the MAF screen (instructions in Techinfo).
5. Using intake-safe cleaner and a toothbrush, thoroughly clean the IAC and TB. Pay particularly close attention to the IAC seat and passage.
6. lightly oil the throttle plate pivot and IAC shaft/spring.
7. Re-assemble. Re-install the MAF sensor only after you're sure the cleaner is completely dry.

Hey will, Do you pull the 8mm bolts from the top of the TB and torque the black peice up, Or remove the Exhhaust heat sheild and pull the black peice off? I've dont it both ways and I think you can guess which is easier...

It'* much easier on an L67 than an L27. I've done mine twice, and an L27 3 times now. On the L67, it'* easier to remove the heatshield and go from there. I can have my TB off in less than 5 minutes. And no busted knuckles. This includes 2 extra heatshields that the car didn't have from the factory

Ok, a couple more questions.
What is an IAC? I don't know that designation.
What type of cleaner is best or just ask for an intake-safe cleaner at the parts store.
Thanks for the help so far.

The intake cleaner will clearly state on the can Intake Safe or Sensor Safe. No carb cleaner whatsoever.

I used carb cleaner. I just didn't get it on the MAF sensor. If you plan on cleaning the MAF sensor, get some throttle body cleaner otherwise, it doesn't matter.

Not a good idea. Don't use TB cleaner on the MAF. It may leave a residue that will bake onto the MAF wires.
Don't use carb cleaner. It may get trapped in the various passages and migrate after the air starts flowing. It'll also degrade the upper plastic intake on L27'* and L36, and possibly the TB gasket itself.
Intake cleaner was made for a reason, and carb cleaner for another. Don't inter-change their uses.

I'm not here to prove anyone wrong. I'm just giving the best advice I know. Carb cleaner WILL kill a MAF sensor. Get enough in there, and it'll take out your O2 also. This is a delicate area. Pamper it with the good stuff
