Re: Attempts stall, Idle Pulses 600-800 rpms, horrible MPG
What is the best method to trace where VPWR may be shorted to ground?
What is the most likely place (at this point) to check for a VPWR short to ground?
I have been trying to think of everything thats been touched in that engine bay and of what circuit board type components still haven't been replaced. The ICM comes to mind as one of the few remaining not-replaced circuit board parts, but that may not mean anything if the harness is just shorted somewhere.
I have asked tripletdaddy if he can perform a multimeter Ohm test on the same VPWR wire to Ground (batt disconnected) on his 95 3.8L Windstar to get a reference from another vehicle. Hoping he can do it. Would be nice if any of ya'll could try the same test on your year Windstar. Wiswind's 96 would be a good test too... and anyone elses. I know I'm not supposed to see a value reported for this test, but it'd be nice to see if anyone else does cause then maybe its "normal" for possible residually stored electricity in the system somehow.
I think the fact that when the radiator fans turn off and I see the idle blip down once and then again twice EXTREMELY FAST before normal idle returns, shows that all my wiring work and improving of grounds has weakened the problem whereas before it would almost stall. Now it just seems to be a half second to second dip in idle speed.
