Re: Help diagnosing engine problem

Thanks, its all starting to make sense. Did I mention the Cat caught my floor on fire about 2 years ago so I put a new one in. That probably burned out my o2 sensor. Overheating led to a whole chain of heat related failures that I am still tracking down to this day.

Re: Help diagnosing engine problem

Help diagnosing engine problem

My '86 'co II 2.9l has been giving me trouble for the last two weeks. I will be cruising along and then the whole vehicle starts bucking/surging, engine runs rough sputtering and if I give it any throttle the RPM's drop and engine dies. Engine temp rises at this time too, sometimes the radiator boil...
