My e30 is running rich. I just picked it up a few months ago and it's unknown exactly what mods have been done to it but it's not totally stock.
The car runs rich to the point that after long drives I get residue on my bumper. I am going to get to testing things like the MAF and the coolant temp sensor to see why it could be running rich but I was hoping for other suggestions to look into. The fuel economy isn't terrible. It was something like $60 in gas for 8 hours of highway driving (in Canada, so a bit more expensive fuel than the states).
I believe it is running rich because I am getting smoke from the exhaust. I know it's not burning oil because there hasn't been any consumption, it doesn't smell like burning oil, and it isn't blue at all. It smells like unburnt fuel basically.
I am not sure if the ECU has been tuned, it is possible that I need to replace it or retune it but I don't think I should start there with troubleshooting.
Any suggestions would be greatly appreciated. Thanks in advance.
Edit: also, the previous owner removed the catalytic converter. I'm assuming this is because it probably died from running so rich all the time.
