95 f350 std srw 3:55 with bullydog chip.
ok here is the scoop on this thing.When i first start it up and the motor is cold it will purr like a kitten but as it warms up it will start to run rough , the warmer it gets the rougher it runs at idle,but it runs real good on the road.gets between 19 and 20 mpg.Here is what i have done,unplugged chip, no change ,unplugged map sensor and icp sensor no change,pulled ipr and replaced orings and cleaned screen thought i had it fixed,not so,checked reg pressure 55 to 60 lbs,dont know anything else to do.I can live with this but rather not. Sorry about the long post.Forget to say it has 254000 miles on it but it had 217000 on it when i got it and it has always done like this.
Thanks JIM

 

If you can get it on a PSD capable scanner, it would help we could see IPR DC% & ICP pressure when warm compared to when cold ..

 

Thanks Rick.
