I cleaned my throttle body on my C6 2005 and now the RPM's run higher and sometimes it gets stuck on 2000RPM??? Any thoughts?

tennblkc6

how did you clean it and what did you use to clean it? if you took material away from the area where the throttle blade rests it can cause this type of issue.

I used throttle body cleaner using blue paper shop towels to wipe off residue.

You need somebody with a Tech-2 or HP Tuners to do an idle relearn.

Thanks, I will get with a local tunner for help. Thanks.

Big mistake using towel to wipe off residue, not supposed to touch let it dry

I thought I did an extensive research thru my How To Do It Bible (YouTube) and everyone recommended to wipe off. Live and learn. Thanks.

Where did you hear this? He's not removing any material. If anything some brake fluid probably got into the electrical motor housing and might have caused issues.

Rubbing a towel over an aluminum body doesn't do anything.

Could you not unhook the pos. terminal on the battery for about a minute then reconnect and see if it would not do its own relearn.

Bake fluid? what are you taking it would be impossible for brake fluid to get into the electrical motor housing. There is more than just aluminum

Do that and then take a 60 mile road trip; the computer will re-learn and all will be well.

I just purchased a Throttle Body 12570790 for my 2005 Corvette and was wondering if this needs to be tuned once replaced? Diagnostics showed this part being damaged and not sure if I need to take it for tuning.

Thank you all.

If it is a stock replacement then no

Simply cleaning your T-Body will make your ECM have to re-learn the fuel trims---Because you are now getting more idle airflow then when it was clogged---Normally this happens very quickly like 10-15 minutes of idling for the idle to learn out and maybe 50 miles of driving for all your P/T fuel to learn out
If you've driven over 50 miles and it still hangs at 2000 RPM's It sound more like a "vacuum leak" than anything else---which typically will never learn out---
I would check for vacuum leaks around your T-Body---Easiest way is to start the car and spray some "brakeclean " all around the T-Body seal where it bolts onto the manifold
IF the engine tries to die when doing this --you have a vacuum leak---
Get a new T-Body seal and be gentle when bolting it back on--in a cross pattern

How are you going to clean the black stuff off if you don't wipe it off with a paper towel or a cloth??.....

Idle Re-learn: Start engine turn on AC rear defroster, let it idle for 2 1/2 minutes, shut off wait 1 minute then repeat..I've cleaned my TB many times with no problems.
