I have a '03 PSD 6.0 F250.
Its got 131,000 miles on her.
She runs great - as long as the morning temp is above 60 degrees!
The morning start is horrendous! Hard to start, makes a ton of racket, blows alot of white smoke (just at initial start), shift points are greatly extended, RPM's barely climb - doesnt want to accelerate.
But 10 minutes later - all is pretty well.
My mechanic has a 7.3 - loves fords and PSD's - he is baffled. No codes. But he said it appears the engine is only firing 6-7 cylinders upon first start. After that - after a good 10 minutes - the engine runs fine.
Maybe injectors, maybe injector computer.
My question - why is it so rough only when the temp starts to drop? Please tell me its something simple and not too expensive!
