Trying to figure this out..

[kitchene]

1997 f350 cclb 4x4. manual trans.

Basically when I get on it it will sputter a little and slowly accelerate. I have a TS chip and in the 50 and 75 horse settings its a little better than stock, but the 100 and 140 it sputters worse. I have a diy filter and 3in downpipe with 4" open exhaust. Are injectors my problem or??

does it idle smoothly? do you have a stock tune?
check/replace fuel filter and check your FPR screen

Idles like it has a little bit of a cam. New fuel filter and FPR screen clean. Yeah the ts allows the stock tune to be used.

how does it run on the stock tune?

Have not heard of/checked that yet! When it comes out, should there be oil present? Running out? Gimmie the low down on that and how to remove and check please.

In the stock tune it's the same. Like with the high horse tunes, it exacerbates the problem, so it's not as bad in stock tune, but proportionately it is... if that makes sense.

Pull the ICP plug (front of driver side head) inside where the plug was should be NO oil, if there is oil in there, you probably found your problem.

if there is oil... replace the icp and I'm good to go? gonna check it first thing in the morning then disable the GD EBPV because its closing as I go down the road even after it's warm.


I've cleaned that sensor, replaced the tube and even unclogged the connection at the manifold..... wish I wouldn't have now because it woulda made it so it never shuts I think. Thing is makin me crazy.

I work evenings and I'm sick as a dog.... and it's freezing, so I just got up a bit ago. Tryin to talk myself into goin out there and doing this crap... whinning out of the way..

Whats the best way to check the pressure? is there a service port on the pump or anything? I really want to get rid of the mechanical pump but i'm moving and there's just no time right now.
