How long since a tune-up? Any applicable mil codes? You can check those yourself. If it is only an idle issue, clean the throttle-body and idle air control.

It was just tuned up from the previous owner and he said it never did this until it was tuned up. Im thinkin the firing order is wrong

If you think you have a dead cylinder, check for a dead cylinder. You kill the cylinders one at a time, quickly, If the cylinder you kill has very little or no effect on the idle rpms, that cylinder is dead or weak.

What about the firing order? You seemed to think that was the problem?
