Hey guys Some info on the car in question: 95 VS commodore, manual, l67 conversion + mods. The issue: Just wondering if anyone would have any idea on where or what to look at that would cause my car to hunt at idle. It is probably the reason my car also has a DTC 76. I've searched for vacuum leaks but haven't found anything. I do plan on replacing every vacuum line anyway, so if anyone has a diagram for an l67 or even knows what size hoses are needed, that would be great. Also, the car has a (what feels like) misfire when coasting at around 1500rpm, in any gear. So far I've replaced the dfi module, CAS, o2 sensors, purge solenoid, IAC valve, PCV. I've checked the spark plugs and leads (with a multimeter), injectors all work. Not sure where else to go. Just need a little bit of guidance, I've searched a fair bit and I've fixed what I thought it could be, short of pulling the motor apart and replacing gaskets. I am looking at doing compression testing through the week and probably buy a diagnostics cable to see if I can get anymore info.
