Hello All, Recently replaced Bank 2 Sensor 1, PCV , and a few vacuum hoses around intake, cleaned MAF and new air filter. Check engine light was on. No light now after 700 miles and passed inspection!! Idles at light around 7,300 Idle has started to run rough a little when stopped at light. Bounces down to about 6,000 but will com back up. I also noticed will will jump, for a second, to 9,000 when stopped and then goes back to 7,300. I have to apply more brake pressure. I disconnected the IAC during a cold idle and the RPMs drop, runs rough, but doesn't quite stall. Plug back in and all Okay. No Codes so not sure where to focus my attention. Any thoughts??? Thanks!
