My mistake, you're right on the engine size

Well we changed the plugs and ran fuel injector cleaner thru. While the car is running more smoothly it's still loud and the check engine light is still on.

We changed the wires both times and the distributor cap but I don't think the coil.
I am taking it in to Econo Lube and Tune today, will have him oo plugs and wires and will ask for the plugs back to check the condition.
Will let you know how it goes.

Does anyone know why the same plug #4 would go out 3 times in less than 55,000 miles. Dealer says not a warranty issue and charges me a fortune to change the plugs, wires, rotor etc. I say it's not normal for same one to go out. Seems to me if it can't be fixed, I should just go to the local tune up...
