It was recently -40 degrees F, and I started my truck to warm it. I have a battery warmer, block heater and oil pan heater installed. During the idling, my idle rpm's dropped to below 500 and I started to have black debris come from my exhaust. The exhaust smelt really rich. I drove it home, approx. 2 miles and the check engine light came on and would blink over 30 mph and I experienced reduced power. I changed the spark plugs over the weekend and the 4 from the drivers side were completely black and dirty. The 4 from the passengers side looked normal. I unplugged battery for 20 minutes, re-hooked it and check engine light went away. I ran the truck today for 20 minutes. At first it was like normal again, then when I pulled into my driveway, the idle dropped again and the truck shutoff and the black debris came back out of exhaust. Any ideas?
have the same problem?
