I don't know if this problem I'm having is an injector issue or ground issue or coil issue but maybe u guys can help. i have a '92 cruiser it has the 150 hp motor in it w/ 180 k, whenever its cold driving in the (d) drive accelerating promptly i get a bad shudder out of the engine, like its "loading up",and it almost dies, so driving in (3) third its a bit better, the only way this problem doesn't occur is when i start out in (1) first gear and shift manually. unless i warm the truck up for around 30 minutes i don't have this problem. at first i thought the harness to the coil was showing bear wire again, but i check my home made harness and its fine, Ive used injector cleaner many times, and replaced the fuel filter a couple of months back. the fuel sock on the pump has been cleaned by me and a bottle of carb cleaner. driving on the freeway it runs great, its just getting there that seems to be the issue. any ideas would be great and if you need more info let me know. thanks.
