So I have a 87 with a 7m that was running, but smoking from the turbo really badly. Also before the smoking issue I had an issue with the CPS that I changed and it showed me the smoking turbo issue because it actually started running the correct way. Now I've changed the turbo with one that I was told didn't smoke... Now when it starts it pours white smoke and smells so rich I can't breathe in my garage. AND now I've got freaking code 12... CPS which makes no sense to me and code 51 which I've had... Had it when it was running. Already replaced the KS with a coax and soldered it in to the ECU side and everything. Also is it possible that when I put the CPS in, the timing is off and it is causing the smoke and the code 12? Thanks in advance for any help anyone can provide.
