1994 chevy silverado 5.7 tbi with auto tranny and 232,000miles. I have replaced the egr, IAC, TPS, coil, cap, rotor, plugs, wires, fuel filter, temp sensor, rebuilt throttle body, and checked for vacuum leaks. The truck just blew an intake gasket about 10,000 miles ago, and repaired it. Now, the problem is there is still alittle missing while idling, and a bad smell like alittle of unburned gas or something coming out of the exhaust. What else would be wrong? I think that the cat has been replaced but i dont know when. I also have no check engine light coming on, so it takes the easyness out of it. Any help would be appreciated.
