Richard,

Maybe you have a problem upstream of the diagnostic tree and coding. Maybe that car is lying to ya.

The worst GM nightmare I ever ran into was on a little car about like you are working on.

Darned thing had been to every garage in a 300 mile radius. Nobody could figure the thing out. Just wouldn't run on more than a couple of cylinders and was very sparadic. Sometimes okay, other times, the rascal wouldn't even pull itself.

I fought it for a week before I finally ran the numbers. The silly thing had the wrong ECM in it. It had originally been a california car and needed the federal emmsions ECM.

Dropped the correct EMC in the dude and it ran like a new one. :>)

Allan
