no aftermarket flywheel
i installed the utec and parts, but never had this happen until after it was tuned and the utec was on. i never ran a map on utec before getting it tuned. bill knose from i-speed california tuned it thanks for the quick reply |

at idle, it will be in the 0 column...which if tuned right, should be 0 anyways...so putting it in map 0 wouldnt do anything.

Mine does this. It has done it from day one! It seems to happen when it starts to get cold out. I think it has something to do with the switch from normal summer gas to the winter formula.

More than likely since it is a little cooler out the ECU needs a little bit of tuning at idle. I guess the air temp corrections I have in there are not working as well as I had hoped. I can help you out with that, just shoot me an e-mail. Though also check for vaccuum leaks as this could also be a problem.
