my car was running good.I replaces parts in the rear-end and gap plugs at 32.now car runs really bad like a plug is bad.it did rain night befor so maybe a bad coil or cap.I had car running really good before i worked on it for about 2 weeks but i started it everyday.when rain stops i will pull plugs.Any other suggestions.my maf meter is couple years old should i clean it.filter looks clean but think i will clean both.I had a quarterhorse tuner in it but i removed it so car is running off fact tune.but it was running really good when i parked it.thanks for any help
