Hey guys, Ive been lurking on this forum for awhile trying to figure out this issue but Im at the point where I have no idea what else to do.
So Ive got an 01 Cobra that has the 1500+ idle surge problem. Im pretty sure Ive done all the fixes that I found here. I replaced the TPS and IAC. I changed out every vacuum line I could find and I did a vacuum test on the manifold with no leaks found.
Where Im at now is I bought an IAC Restrictor and installed it which resulted in the car idling at 1600 nonstop. So I widened the holes to 7/16 and now the car struggles to stay running when its cold. Once it warms up it wont try to die but I still have the idle surge when driving and now Im throwing P0171 and P0174 codes.
I am at a loss with this. I really wanna push this car off a cliff at this point so any advice would be helpful. The only mods on the car are a CAI, Accufab TB, Catless X-pipe with flowmasters.
