well, my car started not starting...it still has the 500rpm fluctuation at 2500 rpm and again at 3700 rpm, but now its like i got worse, sometime it wont rev past 400 rpms, i would have to restart it. then it would start then die, and it would start again and slowing climb up to idle (900rpm), while i would have to floor it...ive changed the coil pack, asd relays, spark plugs, wires, and the cam sensor IAC. The only things i havent changed are the fuel filter and the crank angle sensor....so now it wont even start, it would just keep turn over, and over again and again....the ecu did throw a code for the crank sensor, so im going to change that and then see what happens
