1999 RX300 p1354 on/off
Hey Guys, Ive been lurking trying to figure out this issue with the my rx300.
When I got the car it has some problems that have been fixed, I replaced the a/f sensor, and the both OCV sensors and started running great. I keep getting the p1354 and random misfires( all on bank 2) it comes and goes though, runs great until the CEL comes on then high idle(1000-2000 rpm) and jerking and mixed speeds. It goes away after anywhere from 30-50 miles. Even when the check engine is on I still get good gas milage, and it runs okay.
No sludge, and I thought it maybe the timing off a little so I took the timing case off and everything lines up perfect. I read somewhere it may be caused by a bad gas cap although I don't get how(mainly the misfiring). Not really sure what my next step to test is or should I just say the heck with it?
-Thanks Chris
EDIT: I should mention spark plugs and coils have been tested or replaced on all banks.

The thing thats confusing me is that the CEL is turning on/off I didn't think hard codes like this went away without a reset.
