UPDATE: swapped eta from other car to this one since after rewiring my eta the car ran worse than before. with new pumps in, new ovp, battery fully charged, and 2 gallons of 93, it was ready to go and to my surprise after only cranking it a few times, it started up with NO issues at all. a few days into driving the check engine light came on, i ran the code and it came up with the o2 sensor having an issue (code 12 i think?) fast forward to a few days, check engine light still on but no drivability issues, not even overheating. the idle would sometimes go up and down in gear but it hasn't done it at all since the first day i got it running.

fast forward to a few days after that, i had disconnected the battery because the car wouldn't start due to the fuel/ignition cut out that didn't disengage after unlocking the car from the driver door. i guess there's a problem with the driver lock or maybe a sensor is trippin cause it has to be unlocked from the passenger side for it to disengage.

anyways, the check engine light has disappeared since then and hasn't come back on at ALL. with only 60 miles so far on it since the replacement, everything looks good.

i would have put more miles on it, but i'm selling the car so i can crawl get back into a bmw.
