The check engine light comes on, the cars runs rough, then the check engine light goes off the car runs fine. Took it to the shop and they changed 1 and 3 coils, worked fine for two months then the same problem. Could it be the computer?
no, it wouldnt be the computer. Possibly a oil control valve that adjusts timing for bank 1. Those commonly fail.
I have the same problem with a 1999 RX300. Did you ever find a solution?
