Moved from super duty section

Hello all,

This is my first post on this forum that I am enjoying reading very much on the Ford scene, I have been lurking around for a little while trying to educate myself with these trucks but need some advise.

I bought my first 99' F-250 super duty with plenty of miles on the clock but the price was right as it will be a hauler for my new 32ft travel trailer.

Like I said I just bought it and test drove it and everything seemed good so I bought it, then a couple days later when I picked it up I had a 100 mile drive home and needless to say I was a little turbo happy. It was making just below 20lbs of boost peek and never went over 700-800 deg on the exhaust, after some harder driving the check engine light came on but then below 1800 rpm or no boost it would come off, then back on right after gas was applied.

Then after taking it easy for a while I got off the hiway and was decelerating and got back on the gas after the exit and it was like there was nothing there at all, the pedal was at the floor and it just kinda bogged.

I drove the truck today and there was no light on or anything unusual happened except it ran like a turd when it was cold, and from what I have read thats normal.

Does anyone have any ideas if it was defueling and how to fix this?

The truck has the 7.3 banks turbo, banks super chip, banks full exhaust and filter. Also the CPS has been changed with the recall from the dealer.

Also is there a sticky or related tread for "us newbies" that dont know what oil or how to prime after running out of fuel or even very basic diesel maintenance?


Any input is much appreciated!

 

Definitely not a defueling problem.

Since the truck is new to you, you should start by establishing a clean slate; fresh oil and filters come to mind. Once you get it baselined the good folks on this site will help you fix what's left.

Try to get the codes read. Since you got an SeS light...you've gots codes stored..
