hey everyone..i have a 93 vigor gs auto..my car runs well and rides well beside on problem that i am having.. i noticed this when i got the car 3 months ago but it wasnt as bad..basically when i am stopped while in gear by engine will misfire a couple times..sometimes to the point where it will stall..it doesnt happen everytime i stop but most of the time.. it even is worse when i have the heat on..once i have the heat on and i stop it misses a lot more and stalls more often with the heat on. can someone help me with that...o0o and there is one more thing.. when i bought the car i was told that i needed to change the valve cover gasket.. i noticed since i got the car that it was leaking some oil but now more than before.. i am almost sure that it is from the vcg because when i look near it i see oil along the side. i was wondering if that oil could cause a buring smell that i sometimes smell from the car...well please help me with any of these two.. thanks.
