has any one ever had a problem with a ISB Cummins surging when you put it in gear, mine has been doing it for about a year now, and i dont know what it is, i read that my quadzilla ADR might cause it but i am loosing power, no codes as far as a pump think it could be the pump?

i will try to get a video of what its doing.

 

VP44

 

How does it run without the Quadzilla?

Is it a tranny surge or a starving for fuel surge?

 

well the fuel presser 17 max and dont pull no lower than 12 flat out wfo with tq program in the quad. it died twice today when i started it and droped it in gear (chug chug chug die), im ready to get a new pump, just making sure this is the right thing before i drop a grand on one. and im going to send the quadzilla in and see if its ok, or is that not a good idea
havent pulled the quad off to see how it acts, but it has been loosing power, it went from 15.0 to 16.7 so somethings up

 

I'd pull the Quad, and see what happens first. It's a very cheap test.

 

will do test it tomorrow and see

 

yes its 2 month later but, its still no better it still stalling and shuttering now, it did it with the old pump and now the new vp pump, filter, and so on, and no change, its on my last nerve im about to just sell it. i have sunk $ after $ on it and it still stumbles for about a 1/2 second and dies, sometimes pulls thru it, it also jerks 2-3 times when putting it in gear some of the time, warm cold it dont matter ( the adr is not tapped yet)

any one think it cold be a TQ (suncoast triple disk converter) staying locked
i love my old truck but sometimes i want to crush it.
