1988 K2500 Chevy 4x4 5.7 misses under a load while driving but not while revving the engine?
Chances are you have a bad wire or plug causing it ; It is easy for a weak plug or wire to hit without a load ,so if it is time for a tune-up I would replace the wire set and plugs. Check your cap and rotor also. I hope this helps you. Mark Mark thanks for the help. New wires did the trick. Truck runs great. Thanks again!!!!
You have a 1993 Chevy Lumina and when you accelerate to high RPMs the engine starts to choke and then cuts out after a while What could be wrong?
1999 Chevy suburban cylinder 3 misses and than stops and than misses again Changed spark plugs wires distributor cap and rotor cap It will also backfire when driving?
Do you have a engine surge while driving after installation of new fuel pump in a 2000 Chevy Malibu?
Will driving a 98 Chevy cavalier with a speedometer that doesn't work blow your engine or transmission?
It all depends on the configuration of the engine. If it's a mild, hydraulic cammed street engine, probably 3.73 or 4.11. A high-revving roller cammed engine would need more like 4.88 or 5.13. Your goal would be to have the engine at it's horsepower peak or slightly higher when going through the traps.
