Engine/Transmission (1994 - 1998) Buck-a Roo!!

[GOTSOOT]

Gentlemen: i have a `98 12-valve, which i just completed installing a #10 plate and a set of Piers gov. springs. At around 1700 to 1900 give or take a fewrpm`s the truck wants to start "BUCK" along with a touchy throttle. Will adjusting the springs tighter or looser fix my problem or will it be a combination of things. Horse in trailer is getting jealous- thinks i got a filly in the front seat!!

I did 3,000 GSK on my truck and had same problems. Piers told me how to back off each spring until the bucking quit. Under load when I hit a bump I had to either completely let off the throttle or punch it down to make the bucking quit. There is a way to measure, but I just continued to back mine off (looser / counter-clockwise) 1 click (about 1/3 of a rev) until it got manageable again. It's not that tough once you do it a couple of times. If you did the 3000GSK yourself, you understand. Good luck. Jeff in Ohio
