three cylinders not working

[bigray5096]

I own a 1997 3.0 Caravan and three cylinders are not firing. No seem to beable to tell me whats wrong. The Injectors are fine and the spark plugs are fine. Any ideas????

first check your distributor cap... if unsure replace the cap and rotor... if its still acting up... also can replace the spark plug wires as yours might have too much resistance... if still acting up... maybe have your ignition coil tested.. as it could be fried
