thanks for relpying i had looked into all of those things but in the end what i think did it was changing my plugs, and ignition coils on all 6 cylinders and i had a leak more of a damaged throttle body boot .

Not yet,still looking for the problem.Dont waste money on ex temp sensors.I read lots of forums that recommended this,very expensive mistake.I have changed both temp sensors,both upstream o2 sensors.I broke the spider vent system and aux air injection system while I was in there.Have repaired both with flex hoses and stuff I found at work and at home.My running rich only came on after all these repairs.Smoke tests show no vac leaks on the intake manifold.Still looking for the problem.Car is off the road now,I dont use it anymore so its difficult to fix when its not strictly legal to be on the road,plus its freezing in my garage

hi mike, im a fellow driver same year and car i recently got the same too rich in both my banks, was wondering if you got your sorted.

i changed my MAF, and was looking at changing my exhaust temp sensor.
