Isuzu c223T accelerating problem

Postby Adiddas11 » Mon Apr 16, 2018 6:45 pm

I put a isuzu c223T in to my dads s10 and my problem is that when you press on the throttle and then let go it accelerates and doesn't stop untill i shut the car off.

My guess is that it one of three things. 1) the throttle cable is sticking 2) problem with the turbo and engine oil is going into the intake 3) problem with the pump

I can't answer that one, but who rebuilt it?

I'd always suggest ruling out the easy stuff first. That's why Jim put 1 & 2 before 3: ;)

I'd try to rule out the other possibilities. Then, if convinced it's the pump, I'd contact the people who overhauled it.

How about running a string concentration of Seafoam through the system 1st to help dissolve gummed up parts inside the injection pump. The CSD piston may be sticking also inside the housing preventing timing to go to normal until more rpm/pump pressure drives it back into place and timing not advanced.
