Thanks Pizzaguy! I'll monitor how things go before I do anymore worrying. Been running and starting fine "at this time" and just have to see what happens. As previously mentioned I did already put new aftermarket crank and and cam sensors, inspected the relays for hot spots or coil discolorization. Just for grins I used emory cloth on the engine relay contacts. I'll hold off on installing my new Bosch crank sensor. Got down into the low 40's last night so I guess I'll go for a cool morning drive and see if the heater works or not. LoL Don't get too much cold weather here in Tampa. I did change the oil and filter yesterday with a oil suction pump that really worked well. ( No getting under the car! ) Best $25 I've spent in awhile and already paid for itself by doing both my Xfire's.
