I took it to a local injector shop and they put a new injector pump and lift pump in (pressure was a bit low). Truck is running and starting better than it has in years.

 

hey out their i have a 1993 f250 it smoked a thick white smoke when i bought it i put a new t.a.c on it and the smoking went away or so i thought now my truck is smoking a blueish grey smoke not so much white any more does any one have an idea to what could be making my truck smoke like this it a good truck with as much power as the day it was made but it only smokes at idol and when you first start it this is not a constant smoke if any ideas please help thanks

 

possibly a leaky injector, leaking fuel when it sits.... mine was loosing fuel prime as well, replaced fuel lines and now i have more than 100k.... runs awesome.... does smoke a bit on initial start up, but the IP is turned up about 1 1/2 flats....LOL...... really pisses ricers off.....
