I need some help ! I have an 06 GT with Steeda CAI / Diablo~Steeda 93 oct Tune. Had this setup for well over 2 years with NO problems. About 2 weeks ago The Idle started to sound smooth and quiet and seems as if RPMs drops below 500 then stalls. Strange thing is no fault codes are generated and no Idiot lights illuminate. No power / performance loss on acceleration (off the line or on Highway). No delay in throttle response.

I cleaned out the entire CAI setup - used MAF sensor cleaner (MAF removed) - re-charged the Filter - triple checked / cleaned all of my connections. I changed Gas stations 3 times. I still have the same issues. I only have 38,000 miles on the car.

Any Ideas ???? Anyone had similar problems ? How can I have an RPM issue if it is computer controlled and I have not changed any settings. If A/F ratio was off I should've thrown a code.

Did you clean the throttle body?

HazardSports

Not really - I wiped it with a clean white rag & it didn't show any dirt - but what would be the proper way to clean the TB ?

HazardSports

ok, I read the TB thread:

will try that today. Any other suggestions ???

Vacuum leak at a CAI connection, bad TB or TPS(the latter will normally throw a CEL).
Also, see if disconnecting the battery for at least 30 minutes helps.
