Hey guys,

I installed a downpipe about a week ago and recently my RPMs have been starting to jump while im idle at a red light from about 300 to 1000. Sometimes its rapid and you can feel it and other times it just goes from 500-1000. It never fluctuated this bad before the downpipe. I was just wondering if the ECU is still adjusting or something more is wrong?

Let me know,
Chey

no cams other than the stock ones no.... all i have done to the car so far is the downpipe and intake

Did you get the factory ECU reflash?... even that wont 100% clear the idle issues...

Sometimes the idle will jump around on you. I had the facory re-flash, and it didnt really help. I took the car to HB speed and got it tunes. It seemed to clear up a lot of it, and it gave me 70 HP! You should check it out.

The jumping seemed to stop last night so I think it was just the ecu adjusting to the downpipe. I'm lookin to get an access port after this test pipe and tune it that way=p thanks for all the help everyone. Very much appreciated!!!

Check your TB to see if any hoses are off. My car had that problem when a hose popped off. Make sure you check under the TB where you can't see also.
