Whats up? Anyways, the car starts up ok... but it has trouble idling. When the car is cold, the RPMs will jump from about 800-1200rpm randomly and the car almost sounds like its misfiring. When driving around, if you shift to neutral the RPMs fall to about 300 and the car stutters and almost dies, but then recovers. Once the car is warmed up it begins to idle without any problems, except for the neutral issue.
When driving, the car will randomly hesitate or sound/feel like its misfiring. The car always has this problem in vacuum, regardless of gear or throttle input. It usually stutters pretty bad in the vac/boost transition. Once in boost the car seems to be fine. Also, when the car moves from vacuum to boost the A/F gauge pegs straight to lean, and several seconds later jumps straigh to super rich (under WOT). I have a CEL, and heres what it pulled:
1. Manifold Absolute Pressure too high/too low 2. Intermittent/No Camshaft angle sensor at the ECU 3. Timing belt skipped one tooth or more 4. System too lean (bank 1)
I already went over the timing, and its dead on. I replaced the cam angle sensor, the MAP sensor, and the missing link. I also replaced all the vacuum line connections between the FMU and the intake manifold, the plugs (gapped at .065), wires, and coil (screamin demon). I havent had the time yet to get out with a datalogger and a FPG to see how the fuel pressures are. I have the stock injectors, a Vortech FMU, and the e-manage for fuel management. Im sort of leaning towards a fuel filter/fuel pump/fpr problem... but if thats not the case, Im stumped. Anyone have any ideas as to what might be wrong, or what I can do to better diagnose the problem? If you need any more info about the car or the setup, please post up. Any help would be greatly appreciated. Thanks!
EDIT: I also lost the little filter that goes into the missing link. Where can I get another one, and would not having one cause a problem?
