PostSubject: Chasing an odd miss.   Sat Aug 02, 2014 3:40 pm

I am still chasing an odd miss in the GRiSO, and I am looking for suggestions
what I have changed:

plug wires
crank sensor (I had one off a wreck)
coils (ditto wreck)

My stepper does appear to be malfunctioning but I do not think this is related (this seems to be my idle issue)

fuel filter and pump output seem to be ok, and there aren't any fault codes coming up.

Plugs are new, wiring to the coils seem to be sound i have run the harness and back probed the connections to the coils.

returned ecu to the 068 map and factory default all the way round.

what am I forgetting to check? would the stepper crapping out do this as well? thinking it should not.

What about the ECU harness? Have you checked the ECU pins for grunge or oxidation?

the ecu and dash connectors are clean as a whistle , no bent pins etc.

I have not been able to isolate it to one side or the other either, but it is persistant from idle to redline, it is another little niggle that has always been present but been getting worse.

gonna bench test the injectors next I think

You can test the injectors with GuzziDiag. Might show up something?

I'm back to the grind tomorrow. If you want me to slip that stepper in a bag let me know. I also have a spare pair of 'Jecters if you'd like me to fling them in too?
