So I got my spark plugs replaced by a couple students at the college I attend. They told me I would need to replace the spark plug wires. When I got the car back the other day, the idle was really shaky. When you put it in drive and release the brake a little the idle shakes. I replaced the spark plug wires but it still does it. My dad suggested that it could be a damaged or broken plug or one of the wires is switched. Does anyone have a diagram of how the wires are supposed to go? I looked through the service manual and can't find anything on it. I suppose it is possible that they accidentally swapped one of the wires and when I replaced them today I did the same thing. Also, any idea how much a mechanic would charge to replace my belts? Thanks so much! Jimmy BTW: It's an '88 V6.

Hey everyone, I'm new from Idaho and needing some info on my '89 Pathfinder. Hope to find it here!
