reading a misfire on cyclinger 4? I've changed spark plugs, spark plugs wires, coil, fuel pump, fuel pump filter, muffler....everything....and my engine light keeps coming on....how can i rest or find out the problem?

I take it that the parts stores were very happy to tell you that the code was for a cylinder misfire, and they were even happier to sell you all the parts you bought without further diagnostics. Time to have the injector checked, eh?

Just think how much money you could have saved by having a shop diagnose it.....which is what you now need.
