Try cleaning your MAF so that you get an optimum air/fuel mixture.   And, while you are at it, replace the stock air filter with a K&N.   Welcome to the site.  Drag up a chair and stay awhile.

if it was a maf his idle would be bad also...duh... try your TPS if not that check all your plugs and wires..most likely it will be a bad plug or wire

Sounds like a wire problem to me.
