98 540i issues
I'm currently getting 3 error codes.
I think. My OBDII scanner won't show me anything once unplugged.
I know what all 3 codes mean but I had these codes a few days ago and have replaced injector number 4 with a brand new one. The wiring and everything looked good when I replaced it. The car only has 99k on it.
Does anyone have any ideas why these code would return after replacing the injector?
I could understand if one of them returned it could be the coil or spark plug but I'm still getting the code for a bad injector when I replaced it yesterday. The car ran fine for the rest of the day but when I cranked it today it is giving me the same errors I had at the start.
Any help would be appreciated. I bought this car just over a week ago and don't mind working on it but replacing something and then getting the same error 2 days later is annoying.
FYI yes I cleared the codes, the first 2 stayed gone yesterday and then returned today.
