I just finished installing the DASC on my 97 M44 and I'm having a few issues. First, the idle is really rough. It bounces betweem 300 to 800 whenever I come to a stop.. after a few seconds it usually hangs around 500rpm. The engine light comes on, checked it, only code that it's giving me is the intake air temperature sensors doesn't seem to be working..
Took the car for a drive, it seems to be pulling hard but I'm not sure if its what it should be since I've never been in a DASC car before. My boost gauage doesn't seem to be going past 4psi.. no matter what.. hits it at about 2500rpm and just stays at 4psi.. could it be a faulty boost gauge or is that a stretch? Its hooked straight on one of the two nipples on the manifold.
Any help would be great. Could this be a vacuum leak that's causing low boost?
