I thought I bought a truck with bad head gasket. It had no thermostat and after driving it for about 10,000 miles it showed the signs. I pulled it down to the heads and it looked like just the rear of the intake gasket was leaking. Had the heads completely redone, and replaced anything that looked worn. New belt, hoses, cap, roter, plugs, plug wires, pullys, oxy sensor, throttle position sensor, oil, oil filter, air filter, pcv, fuel pump, temp sensor, temp gauge sensor, thermostat, and loomed all wires. The truck starts and runs great until warms up. The truck has never used oil or smoked and ran really strong before repair so as to think the bottom end has some miles left in her. After it warms up it runs really runs rich then, runs like crap, then dies. The engine light comes on but with a jumper wire only show the "12" code. I don't have all the electronic diagnosis equip-ment to check by the book so looking for which things to replace first. I hate to spend much more than I have to. Map sensor? Knock sensor? EGR? EGR valve?
have the same problem?
