1994 chevy p/u will start and has decent idle but backfires if I acccelarate a lot. The main issue I have is that when I put it in gear it loses power, backfire, won't go past 40mph,won't go uphill. I have replaced fuel filter,pump,spark plugs
and wires and the complete throttle body.
JA: Is the power loss consistent, or does it fluctuate?
JA: What is the model of your '94 Chevy?
Customer: 1500, v6 vortec 4.3l
JA: Are you fixing your vehicle yourself? What have you tried so far?
Customer: Yes, I put in a complete T.B, fuel filter, fuel pump, spark plugs, spark plug wires, check for vacuum leaks and reset timing.
JA: Anything else you want the mechanic to know before I connect you?
Customer: The truck was not run for 2years, so I put new battery and replace the old, stinky, discolored fuel.
