I have a 95cav and its chugging like hell... Im not getting any spark from one of the plug wires. My coil packs are new and my wires are new. Does anyone have any idea what it could be? im thinking its the computer again, but I dont know. could anyone give me some ideas please?

bad wire ? replace the dead one with one of old to test . check continuity of new wire if you have a multimeter

what about the spark plug itself? have you replaced those?

No, but there is no spark from the wire itself.... all others give off a spark when pulled off the plug itself. I can stick my finger in the socket iteself and not get a shock.

yes i just realized i wasnt paying attention, the spark plug has nothing to do with this, the problem is obviously somewhere before the plug

Yeah, but i replaced the wires because i was having this problem. I had the computer replaced last year cause it was doing a similar thing, but only when it rained

I get what you're saying, but what im saying is, the coil packs are brand new and the plug wires are new...... and im having the same problem with the old wire too...

What engine do you have? It sounds like an ignition control module to me.

Check the opposite spark plug in the firing order. A wasted spark system requires that BOTH the plugs on a coil have proper gap, are not shorted to ground, and have secxondary wire continuity. Removing a plug wire and not finding spark can indicate that the plug paired to the one in question is a problem. For example, if the #1 plug wire produces no spark, check the #4 plug. If #3 produces no spark, check #2 (Firing Odrer = 1-3-4-2).
