[QUOTE="Evox, post: 1042461, member: 74754"] The cheapest and easiest thing you could try is to do this. Disconnect your battery overnight. Or disconnect your battery, and turn on your headlights. I know that sounds crazy because, of course the lights actually won't come on, but what your doing is draining all the capacitors in your truck's memory. After 10 minutes or so, reconnect your battery start your truck, and let it idle for 10 minutes. Your PCM will have to relearn where everything is, so it might be rough at first. After you let it idle for a few minutes, with the truck in park or neutral, run your engine up to around 3000 RPM and hold it there for two or three minutes. Again, things might sound a bit rougher than normal. Your PCM is learning its values again. After a few minutes of doing that, turn on your AC to the max and run your engine up to 3000 RPM for a couple of minutes. If that all goes ok then go for a short drive. I'd do that before digging deeper. [/QUOTE]
