Consumer Description

UNKNOWN, I recently purchased it from a dealership in Lemon Grove Cailfornia. Ever since I bought it,it has never had a catalytic converter and only one muffler. It is a 2.7L motor DOHC and requires 2 catalytic converters and dual exhaust due to the double overhead cam. It has cause motor oil into my engine block and has coughed my heater core. Also blown head gasket. I have hired certified ASE mechanics to replace parts and then I run into another problem.
