how did you know it was the computer? I replaced the distributer, plugs, wires, cap, rotor, fuel pump and all the relays. I even had it hooked up to a sun analyzer and nothing. It has a nasty miss and the fuel pump does not kick in right away i have to turn the key back and forth 5 or 6 times for it to kick in. The voltage drops when the jeep misses.
