car-savvy people, please help me!!!!!

I'm not particularly car savvy per se, but i doubt it's 'bad gas'. It sounds to me like a bad distributor or distributor cap. since this component distributes voltage to spark plugs to fire in proper sequence, a faulty one can cause problems like the one you are having.

Other than that, it could be that you need to replace your spark plugs, or that you have fuel line / fuel injector build up (corrosion / deposits)

Yeah, that covers it. I had to replace my cap and rotor a little while ago and now my truck idles fine. If you have a mechanic put the computer on it and it shows misfires in all cylinders then it is your distributor. It's either gas or spark.
