My 3.0 ranger sometimes bogs down at idle, acting like it wants to stall. Wierd thing is, it only seems to do it when I come to a stop. Ive never have been idling at a light and it just bog down, it only seems to do it when I come to a stop.
One of my buddies has a mechanic as a neighbor and he says I could just need new spark plugs and wires. Ive replaced my serp belt and cam sync last week if that makes a difference.

oh and it doesnt actually stall, just acts like it wants to for 3 seconds and then goes back to normal.
