____________the truck was running excellent up until this day. i was slowing down to 60kms from about 80 and started feeling chugging and sluggish throttle and then noticed the white smoke, i stepped on it a bit and got back up to over 90 and seemed to run fine again and no smoke but as soon as i slow down all hell breaks lose again and even worse at idle. no coolant smell new pmd new fuel filter lift pump has been swapped with new one lots of fuel at water in fuel port. cut out the cat thinkin maybe exhaust was plugged and thats not it either. im thinking injector pump but i hope someone can steer me in a cheaper direction than that. thanks to all...i am new on this site but have learned alot from it in the last few days_____________________
