ktmrider Posted October 10, 2010 Share Posted October 10, 2010 Yes. Instead of the Toyota term you used try AVCS and OCV ( oil control valve ), there is LOTS of info about it in this site. Link to comment Share on other sites More sharing options...
blongo804 Posted October 10, 2010 Author Share Posted October 10, 2010 Thank you! So replacing this seems to be the way to go. Long story short, we bought the car with a blown turbo and one OCV was replaced on the cylinder 1 & 3 side so we're assuming the OCV on the 2 & 4 cylinder side will need to be replaced. This is just the first assumption at our problem here, we're still investigating a true cause to the 2 & 4 misfire. Link to comment Share on other sites More sharing options...
BLACKeNeD Posted October 10, 2010 Share Posted October 10, 2010 Could itpossi be getting stuck? I pulled my OCV's and just cleaned the 2 of them, and no more misfires. Link to comment Share on other sites More sharing options...
