first of all if i was u i would get a code reader for about 100 bucks you can get a pretty decent one.that way u can read the engine codes when the engine light comes on and have a better idea on what to focus your attention and money.other than that is like being blind on one eye and cant see out of the other.if the engine is misfiring it could be out of time or a bad distributor coil or a crack spark plug wire or the wires are crossed on a chevy the number one bank facing the driver side from the front of the vehicle is 1,3,5,7 and 2,4,6,8 on passenger side.just to give u some idea of the complexity of the problem.a code reader would go strait to the problem.good luck
