11lb pulley/new maf,injectors, car won't idle...help!
1998 Cobra, I've been running a procharger 600b with stock injectors/maf/fmu/6lbs of boost with no problems.
Got done putting on the new 11lb pulley, 30lb injectors and a pro-m maf today and the car won't idle. If I give it a rev it just wants to die after, or might run with surging idle for a while. Sometimes it will idle ok though....I'm lost. Vacuum reading is steady.
There was a hole in one of the fuel hoses, so I have the FMU off for now until the new hose gets here, but all vacuum lines are plugged. This wouldn't affect idle though, right?
One last thing, can I go back to the stock maf with the 30lb injectors? I thought I had to have the right calibrated maf, so I bought this one, but the old one seemed to idle fine. Does the FMU compensate for a MAF calibrated for smaller injectors?
Thanks for any help. Al
