ECM Bad after 2 months

Are you positive it's not an ECM grounding problem? It tends to be a recurring problem with GM's.

Ground wire seemed tight & clean.

There must be multiple ground leads/wires in the ECM connector & wiring harness, no?

I'll be checking more wires tonight & tomorrow, tearing off the black plastic loom in different areas. Last night I brought the car to the goodwrench Wednesday night. The car would not accelerate. He tested the coil & said one of them was showing 8 ohms and 10-11 on the other two. I think its supposed to be 14 ohms.

At least this laatest ECM seems to be alright, no stalling when you slap the ECM.

Put a new coil pack ( AC Delco - made in China, $96 ) on today the car run great for 3 hours, I went to Walgreens around 2pm and the car was hesitating going there, had to keep my foot on the gas, in front of Walgreens it shut off by itself.

No problems starting the car.

I'm 73.1% ready to trade it in.

The coil ohms are 11 (eleven) on my 3.3.

There's a '04 Caddy DTS waiting in Madison, WI :-)

Tonight the car run like it was on the oval at Indy.

It must have known what you were thinking. Sometimes driving them past shredder at the junkyard helps. But if you feel a tug in the wheel towards the entrance as you drive by, it is time to get rid of it. Sort of like a Weegee board.
