replaced coil packs and spark plugs. was getting an intermittent misfire on 2 cylinders in the AM when it was cold outside. then the misfire became more constant, anytime punching the gas, going up a hill, etc. running smoooooooth now.
seems like these go out between 60-80k miles. replaced all 8, now i have 6 spares
still waiting for weather to warm up before tackling the alternator mount gasket...
