92 98 Regency Shaking

My car was running in park when after about 7 mins it started to shake and sound rough. I turned the car off for about 5 mins and started her back up and it was doing the same thing. It barely picks up speed on the street but it does on the highway but once you slow down it starts to shake and run rough worser. When I finally made it home the car started to stink but no smoke was coming out of the car nor did the temp light come on. The compressor kept running longer than it normally does once the car is turned off. Could I have put bad gas in the car or what please HELP!!!!:banghead:


It turned out to be one of the egine coil packs was bad.

Possible engine miss from plugs or wires, posssible rich mixture from a bad maf, possible cps going bad, the problem is too general for an exact remote diagnosis.
