hey everybody, quick question. I think that I may have a bad primary injector. the car runs fine at all times except idle and start up. I need a good way to diagnose this problem. I was thinking of disconnecting the pressure sensor hose and plugging it to force the secondaries on. If my idle smoothes out a bit that should be it, no? after that i guess I'll throw a ground at each of the primaries to determine which one? Does my thinking sound correct?

 

A totally bad primary will cause a very hard start, no idling (except with your foot on the gas), and very rough running...

 

what about a clogged primary thats not properly atomizing the fuel?
