Hey guys I posted a while ago about a surging problem, well it got worse. so far i have changed the tps, iac, rotor and cap, coil, fuel filter, and cleaned the egr and throttle, changed all spark plugs, check wires for spark leaks, and check for vacuum leaks when it was running. I have had no luck only thing i can think of is the fuel pump at the moment. I can hear the pump whirring when i turn the key to the on position. So any input would help so i can get my car started again. Thanks guys!
