my buddys car at school is still messed up, hes had new plugs, plug wires, cap, rotor, new distributor, new fuel filter, and catalytic converter isnt bad, hes put the best injector cleaner money can buy, and it still is missin out. could this be a sensor somewhere? or maybe the fuel pump?or possibly a burnt valve or blowed head gasket?

get the injectors serviced and see if that clears the problem up.

Lots of things could cause a miss, why not take it to a shop, pay 70 bucks and find out for sure. It's alot cheaper than just throwing parts at it and hoping it will get better.

My car did the same thing amd come to find out it was my o2 sensors and a fuel pump relay that was the problem. Try checking those two and maybe that can help you out a little. If not it may be the fuel pump or the alternator is going bad.

Check the ignition timing, check for a vacuum leak, make sure the ignition wires are good. If the plugs arent gapped right this can happen. Give it a compression test, low or uneven compression can also cause this.

could be aftermarket plug wires and cap and rotor....i have seen it before...aloso check the timming its possible that the timmin belt has jumped....and if only a tooth your ok if much more then the engine will be toasted
