Hey guys I put a ported TB on my car and now it seems to idle high for about 3 seconds or so after start up and if i hit the gas what could be the problem??? Also nothing is sticking could one of the sensors be bad??? if so which one do i check first or could tuning the car make the prob. disappear??? Thanks for any help

You have to be more specific.

It idles high after you hit the gas? That sounds pretty normal.

How high does it idle once it's started?

Well I noticed it after the car reached operating temp. it will idle at like 1400rpms for like 4-5 sec and then drop back to normal idle after hitting the gas any clue???

How long has it been on the car, and how long has it been doing this?

You might try disconnecting the PCM for ~30 minutes and then letting the car relearn its idle. You might also have a vacuum leak after putting it all back together.

No leaks that I can tell everything put back to norm. just started doing this after i put on ported TB if I put the stock TB on it's OK. Been on the car one day

It sounds normal to me. Hell, my A4 would idle @ around 800-1k rpm for a second or two on initial start up then it goes down to 500-600 rpm. This is w/ non ported and ported TB.

Its not just on start up even after driving it will do it

Yeah, mine will stay about 900 coasting after I accelerate then it goes down a few seconds later when I stop.
