[QUOTE="JD3020, post: 674245, member: 373"] My truck idles nice and smooth when cold, and like a complete POS when hot. Can't figure the damn thing out. LOL Basically changed everything except engine mounts, a few small/random sensors, and the PCM. But i'd go through and check out every plug and wire. Last week I helped on a buddies truck, where every UVCH, except 1, was burnt up up at a GP pin. One was bad enough that the plug was melted into the gasket, and it was shorting and cutting off an injector. May not be your issue, but wouldn't hurt to check. [/QUOTE]
