OP, not trying to thread jack but everyone reading this seems to have a similar issue. I’ve been having misfires and burning through o2 sensors like crazy. I’ve replaced every component I can think of apart from the SAP valves. My car is tuned and the SAP is disabled but it’s still not running right. I didn’t want to replace the SAP valves with new ones and run into the same issue later on when they’re not necessary for my application. I have finalized designs for a GT4 block off replica. I was going to have a set CNC machined for myself but if there’s some interest I’d be more than happy to have a few extra sets made up. If anyone is interested shoot me a pm.
