73mm bbk throttle body idle surge
I just installed the BBK throttle body last night and before installing I disconnected the battery, pulled fuse 47 and 3, then began install. After install I hooked everything back up and proceeded with the idle learn procedure. It stayed at a constant idle of 1300+ but once I put it into gear it surged to 3000 rpm and would hover between 3000 and 4000 no matter what gear I was in.
For instance if I was in 5th at 40mph the engine kept pulling to get to 3000+ rpms. A code was thrown and car went into limp mode. I believe the code was IACV or something along that nature, I looked at it but figured it was some sort of vacuum leak. I then took everything apart and reinstalled making sure everything was tight and snug.... Same problem...
Soo off to old reliable, aka the original throttle body, and voila no more issues!
Anyone have this issue or would be able to pinpoint the potential problem before I send it back to BBK? I checked the Drive by wire and all gears are moving and flap is operating fine and I couldn't install the throttle body much tighter to the intake manifold without stripping the screws..
BTW my only mod that would affect this is my JLT CAI, which was checked before and after every install..
