Hey Gang, Well I helped my friend install his 4 GSK in his '98 12v automatic 4x4 truck today and ran into a little hiccup.... All went well up until we started the truck up and it had jumped from idling at 650rpms to 1000rpms so we adjusted the idle adjustment back down to about 850 RPMs.But the real problem is whenever he puts the truck into gear (auto) it dies.... It does it in both drive and reverse. It drives fine down the road, really moves!!!!:drool:We measured the studs you're supposed to measure on the truck and the starting measurement was about .015 and the nuts were relatively loose. We installed them at .040-.050 like the paperwork said. They are about at .045 and the other at .048, give or take a little.Now we also kept reading about some shims... the truck did not have these shims in it that we saw and the factory sealing paint was over the retainers as well and hadn't been broken either....:shrug:I suppose the real question is do we need to tighten the retainers up? Or do I need to loosen them up? Or something else??? This is his only truck and it is a real pain for him as it dies at every stoplight and sign!!!! Any help would be awesome!!:pray:Thanks,Winslow
