i sea-foamed my car...followed directions> put it in, wait 5 minutes, then run.
when i started it up, it ran REALLY rich and black smoke shot out the exhaust.
i thought it was suppose to do that...but after 15min it didnt stop surging and running ruff.
pulled codes from my ecu...got #12. >>>89 ka24e
its the air flow meter circuit.>>>can anyone help me on fixing this?
where should i start??
tried searching...also relays, fuses.ect swapped out the MAF and still running ruff.


thanks..
