It appears as if the engine is running lean in the high end when warm (Engine seems to get overly hot). QUIT ruining this wonderful car! This engine is the BEST of domestic small V6 engines! It is BULLET PROOF and should get you 30 MPGS all day long if tuned correctly! DO NOT hot wire ignition You will cause MORE and MORE damages instead! You MIGHT have a bad FUEL CUT-OFF really, but at LEAST get a check up before you DESTROY this grea car!. The truck runs great with the exception of bogging down when I step on the gas.
