Hello. I have had my s50 swap of my e30 for about 2 years now and everything has been great, except for the other day i took out the battery for about 10 mins. and when I replaced it the car wont idle and ran real rich. Peake code 1A came up and got Control unit supply. I tried three other ecus, new crank sensor, changed computer relay, checked fuses, new ground wire for the battery, checked harness to make sure its good, checked tps and AFM, also checked for leaks and still keep having issues with it not wanting to idle and revs real bad. I clear the code and even with no code reading, the car runs like crap, if anyone can help point me in the right direction that would be awesome.
