When mine did this, it was the O2 sensor that was faulty, so check that and
the wiring for that. If that's fine, I would say, ECU is bad.

Subject: '90 Carat Runs Rough...the epic continues...help??!!

I posted a question last week about my '90 Carat
running rough after heads have been rebuilt...tonight
the saga continues...

The original problem was that after re-doing the heads
and re-installing engine the van runs VERY rich when
it warms up...black,sooty exhaust. I forwarded the
mechanic suggestions from the list...

He swears he has checked and re-checked the grounds,
adjusted the valves, new o2 sensor, air control unit,
and after reading over the emails he went back & went
thru the grounds and wires again.

Ureeeeekaaa....he called and said it was running fine
and was not sure which solution had cured it.

Well....I paid him...got about 7 miles away and it
started running rough again! Seems if I stop & start
again it runs ok briefly then loads up
again...especially when I get up to 50+ miles an hour.

So..I limped it home and will limp it back to him
tomorrow...does this sound like anything anyone out
there has been thru???  Please send any and all
suggestions.

Man...I'm really feelin' like I been ridden hard and
put away wet!
