Engine Performance problem
1990 Cadillac Deville V8 Front Wheel Drive Automatic 127000 miles
My deville has just started running very rough and missing under acceleration, I have tried injector additive but it still stumbles and kinda has a very funny sound like a clyinder is not firing, I notice a slight coolant smell when I turn it off and no noticable smoke out the exhaust could it be a head gasket blown between the cylinders or does it just need plugs and a tune up, cap and wires? I have been running regular gas and add a can of lucas injector cleaner every once and a while, thanks for the help
have the same problem?
