I have a 94 Del Sol that i picked up from a local guy! It has a b18c1 GSR. I reseved it under the impression that it he bought it runnin great and parked it two days after he purchased it. The next morning he went out to start it and i just back fired! Well then i came along and picked it up. I just finally got the time to monkey with it. And i checked the timing seems to be fine. Checked the relays,fuel pump, and timing! everything appears great. So the last check was the plug wires after i noticed a second dizzy in the trunk and i found the wires hooked up wrong. It fired up runs hard check engine light is on, revs up and down above 1000 rpms i reved higher and found at around 4000 rpms it hits rev limiter.
So i desided to check the ecu and it has a p75 for a gsr. Would that make a diference cuz i believe its sopost to have a p72 so yes im looking. Help me please!

Yes you need an OBD1 P72 ecu for starters. After you get the ECU pull the codes by jumping the service connector. UNPLUG THAT ECU RIGHT NOW. It was never meant to run that motor and you need to get the correct ecu. It will most likely solve all of your problems. Take the top half of the case off and see if the p75 was chipped then sell it.
