Why do the truck gods mock me so? I've got a 93 chevy 1500 350 5.7 tbi. I got a used engine, not rebuilt but used. This is the third engine the truck has had. Wife has a lead foot, but more on that later. Started the engine, sounded strong, oil pressure jumped up to 30 psi as soon as it started.
Check engine light came on. Then popping through throttle body. Read alot about timing. Adjusting the timing to TDC as specified in the Chilton's manual. Popping still heard in the throttle. New plugs, new wires. With the engine running, I removed then replaced the wires from the distributor. When I got to number five and removed the number five wire from the dizzy, the throttle backfire stopped completely. I have little to no power when I try to drive the truck and my oil pressure dropped back down to danger zone after I let it idle for about 10 minutes. Should I whip out my compression gauge or should I whip out my baseball bat and try to get the money back from the guy that sold me the crap engine?
Any advice would be great.
