Noooooooooooo, no Delta Feedback. That'd be an easy one. I've already got more money into this thing (time mostly) than I paid for it.
Here's an update: F,F,F,F.
Here's another: Probed the EVP (EGR valve position sensor, another stupid redundant integration designed by idiots) and the Crap Elusive Light stayed off all day. Popped on again this morning after it was warmed up, 6 mile drive to the store, and came on at the restart.
Went under the hood and pushed in on the plug...light wouldn't come back on. When I probe the V-return and the signal voltage is as constant as it ever was...
Back to the junkyard to visit it's brothers and sisters for a plug end.
BTW, JWM59... did I mention F?
