How about the air filter and the fuel filter. Either one of those could cause these syptoms. you could also have a weak fuel pump. But check the filters first and get back to me, Raz

Yes i have a 96 chevy 2500 with a 350 and i cant fegure out what is causeing an engine miss i done repalced plugs wires roter and crank sensor it only mises when driving engins sounds solid at idle


What you are saying is the engine runs rough under load.
If the fuel system is in good condition, the ignition system would be my first target.
You mentioned plugs wires and rotor. Did you replace the cap ?
What about the coil ? The pickup in the bottom of the distributor ?
Any of these components could cause a miss-fire.
Even a faulty O2 sensor could cause a lean fuel mixture.
Is the check engine light on when you are driving ?

Is this a 5.7? They are notorious for intake manifold gasket leaks. When mine did it, the diagnostics blamed it on an ignition misfire also! Replaced the gaskets and it runs smooth!
