loss of paower on incline, runs as if we cold, missing, black smoke
My buddy borrowed my truck to tow a Suzuki Samurai (small jeep) up to Big Bear and on the flats it towed GREAT, however once he got to an incline, he would loose power and it would run as if it were cold (jerky, miss firing, black smoke). He would then pull over and and let it idle for a few minutes (until the engine light turned off) and then start on his way. He would power through the gears like the truck should and then after a couple minutes it would miss again and the engine light would come back on....
I have not pulled the codes yet but I am curious what you guys think. It is a stock truck with high miles ($273k). I have been towing my 8klbs boat with it with out problems. It only acts up on an incline.
I did run it a bit low on fuel the other day and it run like crap. I called the dealer and he said to fill the tank up and let it run for 20mins, so I did and the truck ran great. Perhaps their is a crack in the fuel pump/pickup inside the tank???
I am trying to sell this truck and it has been running great until this!
