All,

There is still just no joy in whoville today!

I did run through my list of items as posted last night, but nothing.

NOID light worked on all injector wiring harnesses, and
TPS was within resistance range at both idle and wide open,
No cold solder joints on the ECM.

So why did pulling the ECM cause it to change behavior????

I do have a small vacuum leak at the boot going into the throttle body, but would this cause the car to not start after it warmed up? I'd love to hear about this.

Also, to add insult to injury now, when I did move the car today back onto the street for the next car in need of maintenance, there was a large patch of oil on the driveway. What might have caused that to happen, any ideas????

I did get the car to get into that state again, but only once. I was however able to start it almost right away. It has a very bad hesitating on blip-ping the throttle, but only after it is warmed up, but this too comes and goes. This hesitation issue is not seen on a cold startup.

I'm about at my wits end and am close to taking it to a good INDY in the area, however the new to me, oil leak is very disturbing and I would like to know where this is coming from before moving forward to an INDY to tell me what the issue is.

As always, any thoughts would be greatly appreciated, even it they are the same thoughts, maybe I just need my head beaten in a little bit more.

Thanks in advance,

Matt
