Ok I have a 1995 f250 4x4 7.3 ps late model. I will be driving along (usually when I have just started the truck) the check engine light will come on and it has no power. It will idle but real ruff for about 20 sec or so then it will start running fine and ill be on my way. Yesterday it did it five times to me so i am getting concerned about it. I am guessing it has to do with the fuel pump .or the fuel injector’s pump?????????
p.s. I hope i didnt leave enything out this is a great form i have learned alot on hear thanks Rob

 

I would scan it first and see what codes it throws and start from there.

 

Did you check the oil? My old truck had a similar situation and it turns out that the oil was way way low and the engine wasnt getting oil so the truck would shudder in a manner similar to what you are describing.
Could also be a CPS (I cant remember of a bad CPS throws the check engine light or not)...its fairly common and pretty cheap to fix.
What codes is it throwing?

 

thanks i was going two buy one this weekend thanks

 

I put a new cps in about a year ago

 

you should definitely scan for codes, since it's setting the CEL. that will give you something to work with, rather than just shooting in the dark.
