Alright here's the deal. Got a 1993 Del Sol Si. I would be driving the car and it would ,BLURP, for lack of a better description. The tach would go nuts right before this. The car will shut off completely driving at whatever speed. Replaced the fuel pump, fuel filter, dizzy, and plugs. Only happens intermittently. Started right up and drove it for 5 miles today with no problem, but then it did the BLURP thing (didn't turn off though). I'm wondering if its the ignition coil or a fuel relay? Going to run the codes tomorrow. Runs fine for a few days, then just horrible after. Suggestions?
