have a 1997 caravan, 3.3 v-6. problem is when running down road at speed limit, motor every once in a while cuts out really bad. it is just like engine cuts off and restarts. had trouble before similar, and changed fuel pump and filters. this time, has a new filter, but not running right at all. even runs rough at idle. has anyone had this problem, and what can i do? also does anyone know of an EASY way to change the middle spark plug on the back side, without pulling half the engine? can change the otherones just fine, but cannot even see this one. can someone please help

 

Might need an injector cleaning or check to see if all injectors are pulsing right. Also make sure your plug wires are seated coreectly and new if you're changing the plugs with more than 50k mileson them. The Middle back spark plug can be reached from underneath . If you got the #1 plug behind the alternator , the #3 is a piece of cake. Lying underneath you can look up the exhaust manifold pipe and get to it with a short extension on the spark socket. Good luck
