Hey guys...lil problem here For some odd reason as im driving my car decides to rev by itself! For example today early morning drove my car, no throttle just crusing and the cars rpms rose and lowered! Id be at a complete stop and it would do the same thing. I would need to have the brakes appied or else the car would jump forward! Anybody know what i mean here?

Car is a 2005 mustang GT AUTO, JLTII intkae, bama 91 oct tune, slp lm, o/r H

thankyou!

 

Vacuum leak?

 

Could be a dirty throttle body or a bad TPS (throttle position sensor).

 

how can i get this fixed??

 

Do what Don W. suggests first. That is the likely cause.

Yep...I had the same issue and cleaned the T/B and presto...no more problem.

 

yeah same here.. Doug wrote up a thread about this very thing a few months back.. just do a search.

 

Here's the write-up from Doug. Be sure to use Throttle Plate & Intake Cleaner (link at bottom). When I installed my C&L Street CAI, decided to clean TB & plate while I was at it. Also, you might also want to clean your MAF wire (with proper MAF cleaner).

I used brake cleaner... worked like a charm.

 

Brake cleaner cleans good and is safe.

 

thankyou so much everyone
