I have a 86 iroc, 305 tpi, AT. I have been having problems with this car lately. I checked for codes today and it came up with 22, 33, 43, 44. The problem with this is the computer has been reset by disconnecting the battery and all these codes came back after I replaced the 02 sensor, MAF, Knock sensor, Electronic Spark control module. I am getting the tps but that is only for code 22 and even if i fixed it, it would probably come back up anyway....is there something wrong with the computer? How can i replace this stuff and then the codes come back?? i don't know what to do with this car anymore......it never stops...someone help....
