I am sorry if this has already been posted. I have replaced the fuel pump, fuel filter, fuel pressure regulator, MAP sensor, throttle position sensor, idle air sensor, crankshaft position sensor, distributor cap, rotor, coil, and wires. Now that you know everything that I have replaced I will describe the problem a little better. I have an extended crank issue, then when it does start its very rough idle and it will die if I give it any gas. After about 30sec it will idle up to 1800-2000RPM then idle down to a rough idle. Sometimes it will do this once and sometimes it will go up and down 2 or 3 times. Anyone have any ideas?
