Alright just finished swapping the Fuel Injectors and reset the CEL. Drove it about 10 miles without the CEL coming on again. Before it would come on with 5 minutes of it idling.
I think I found a leaky vacuum hose while I was poking around, replaced it, going from the electrically activated vacuum control valve that operates the variable length inlet actuator so that could have had something to do with it. I thought I heard a leak back there but must have missed it the first time I did the vacuum lines...
Only time will tell now...
