Yes i did a 4k GSK on a 98 12 valve and i have done these many of times before and no problems?? so maybe i just got lucky the first couple of times but i set the governor springs to as many clicks as what it was when i took the stock springs out...but the idle spring is backed off all the way and it still idles at 1000rpms?? Which i know that means it is to tight??? so i have backed it off 2 more clicks and same thing....?? These things are getting loose it seems like ?? What should the stud protrusion be on the 4k kit?? and also i have always remove all the springs (including the Idle spring) and removed all the shims and no problems??? THis truck is a auto also with a built suncoast???so i know the convertors can pull them down some but not kill it ????i need this truck back on the road pls help thanks !!

 

come on boys help me out !!! if ya can!!!

 

pls help me 49 views no info??? pls!

 

What about the idle adjustment on the back of the pump?
Did you find all the shims, even the one on the big idle spring?
PDR told me it was a NO NO to remove big spring, because my idle drops way down when i let off pedal, they told me I screwed up my pump.
Hope this helps

 

i have taken that out everytime i have done it and it runs fine and the pump is perfectly fine on all of them.....this one has the idle screw all the way backed down.....and it still idles at 1000rpm and dies in gear and has to start with pedal!!
??? so yea read the starting post that i put and help me pls....

 

Are you not using the big spring?
You are told to not remove it. If so, put it back in and try it.

 

did you measure stud protrusion? sure you don't have a shim stuck somewhere?

 

yes i am using the large idle spring.....and i have removed it....and removed the shims behind it....i have done this on all of them and they all worked..??? everything was great on all of them... i have looked for a shim....and i need to know the stud protrusion that it needs to be sat at ?? what is the depth supposed to be sat at..???? thanks clint

 

I always measure stud protrusion before tearing into it. it won't necessarily be the same from side to side. have you tried backing them off each one click?

 

I believe the stock stud portrusion is ~0.05".

 

You want about .050" stud protrusion. Maybe it's the linkage holding the idle up, have you double checked it's not binding. By removing the shims under the idle spring you can give the whole spring pack more clicks, without wrecking the torque back up,[idle & start quaility] but you really shouldn't need to do that unless you are trying to get more than 3 or 4 thousand revs

 

i see i see i have never thought of the linkage holdiung it up and also it didnt matter what it was before i tore into it because thats why we did becasuse it was messed up the previous owner just tighten the stock springs down and everything so yea....lol thanks for everything...
