Engine/Transmission (1998.5 - 2002) Motor surging

[larryj]

I have a 1998 24 valve the truck surges between 45 to 65. MPH

It has been to Three dealers & no one can find the trouble

any ideas I need help. :--) Oo.

LOP, by surging what do you mean, I just posted my shakey truck at about the same speeds while the truck tries to downshift.



Read my post, maybe it will help you also!

What is your fuel pressure doing during this time. Would be nice to know what each injector was doing also, but I suspose that would be rather hard to find out. Anybody out there know how to do diagonstics on the injector pump while still on an engine??? Just an idea. Good luck

Is the motor noticably gaining or losing power? or does it feel like its shifting in and out of 4th ?
