Yes it is plugged in . Wiring will need to be ckecked. Drivers side O2 plug was very oily. I am suspect of it. Oil filter has always leaked a tiny bit. No matter how tight or loose i put it on and I always clean mounting surface and coat gasket with clean oil. IM NOT starting another thread on this . Idle prob is ENOUGH for now. Point being I will remove both plugs and spray clean and reinstall. Thanks. P.S. It is raining here today and I donot have sheltr . No answers today.
