well i hit a huge bump and im slammed. right after my car started idling at 2000 rpm and getting fuel cut off at 3k. well i got a new Idle air control valve installed and that solved the idle at 2k problem, but my car still wont pass 3k. it bounces like its at rev limiter. well any help is appreciated. btw i have a j spec b16. i have the orange cel on but its been on since i got my exhaust since im missing an 02 sensor

Last would a b16a2 timing belt fit on my jdm b16a ?

thanks in advance
