1. hope you guys can help? Bought an 89 bronc and did some changed, mainly maintanace stuff and it's been doing great, however I changed my exhaust (cut out the cats and added 2 1/2 pipe and a flowmaster) and did an oil changed. then, i started to notice gray smoke on a.m. crank up and driving off. Once warm it doesn't happen, unless I jump on it and the trans kicks down, then a cloud of gray smoke shoots out. too much oil added?
2. also, I timed it up without a light and don't know how much? Could this be part of the problem?
3. Lastly, my check engine light comes on after driving in th city for a while? Shut off the engine for a couple of seconds (literally) and the engine light goes off and everything is normal.
I know it's long, however I have to include everything........
89 351w, 160,000.........
Thanks in advance
