I went back out to the garage and triggered the diagnostics. code 2111 - speed sensor problems. I didn't even touch this thing! Maybe I snagged a wire while changing heater hoses? Gotta test these senders tomorrow. Could bad plug wires whivch have gotten wet make it die? I have not changed wires yet - they were supposed to be delivered Thurs, but are not here yet. Thanks again. Samir.
