Engine/Transmission (1998.5 - 2002) Bucking

[mroidt]

Hey guys,



I'm sure someone's had this problem before. You can see



my mods include some Jammer Stage 2, thats when it started.



These are just great driving around but when the



5th wheels hooked up, and after it locks up in OD, it's great till



you give it fuel. If you ease into it, its ok, but anymore than



easing into it, it BUCKS!! This is probably at 60-70 mph.



Now I backed off the EZ to the lowest setting and it still does it.



Is it getting too much fuel for the RPM or is it just lugging it.



It never did it with the stock injectors, maybe I better go back and try



Stage 1!!! I can't belive its lugging it



Thanks for any replies.

i would do a trans service, and adjust the bands. it's an easy job and may fix your problem.

Does it go away when you turn the Comp/EZ off? Your post states you have an EZ. I thought the EZ had only one setting so I am confused and probably misunderstanding something somewhere. Anyways, I had what sounds to be a similar problem. Showed up after I installed bigger injectors (Jammer 3's). It would/will buck very noticeably with the comp on and seemed to be more pronounced when it was colder outside. Not sure if this is the same thing, but here is a link to the other thread.

Graphic man Trans been serviced twice this year and bands adjusted once.

Thanks for the reply .



DLausche The EZ has three setting inside the cover, the lowest being

just a boost fooler, the second for bigger injectors, the 3rd being whats advertised.

I read your post and it sounds like it was the comp box ,

is that what you figured. Anyways thanks for reply, maybe someone else

will chime in with some more ideas since I kicked it back to the top.

Thanks for the info on the EZ. Didn't know there was 3 settings.



Well, I never really did figure out what the cause was. Best explanation I found was that there was a signal fluctuation somewhere (APPS?) and the Comp was what was causing it to be "amplified" so-to-speak. That and the larger injectors that can deliver more fuel make the fluctuations noticeable under moderate to heavy acceleration. I suspect the problem is originating with my APPS signal or maybe the related wiring there. In any case I don't use my Comp anymore so my problem is still there but it's not really a problem to me. I hope you figure your issue out. I am curious if a more definitive answer will be found.
