Code 0200 Rough dile ile

diles?

As you know one of the problems can be the Fuel Cap. I make this suggestion. If you changed your Fuel Cap before the Purge Valve double check that the cap used was an OEM (Original) Chevy Part for that specific vehicle, not just any cap from another Chevy.

Don't throw parts at it

Check the FAD dile on the stereo, push it in to pop out, then turn dile.

check fuel pressure + clean throttle body

Sounds like the lock up torque converter is slipping based on your description of the problem. i estimate roughly 1,250 dollars based on 400 dollars for a torque converter and fluids, and 10 hours labor at 85 an hour.

you may have bad gas which can cause all these problems ...stale gas has a very sweet putrid odor...check that first

have you checked any wires on your altenator
