My car started sputtering off and on for about 1/2 mile and then completely started running rough. It didn't die even when idling and will excellerate with no problems, but it acts like it's misfiring, especially when it's idling. I replaced the wires and plugs and dist cap about a year ago, so thats all in good shape. I replaced the wires anyway, didn't like the old ones. Here's the big hint to anyone that knows much at all which is more than I know. I can pull 2 of the spark plug wires and nothing happens at all. The other two will nearly kill the engine when pulled. I checked the dist cap. No visual problem there. Plugs are good and new wires now. manual says possible vaccume problem but I can't see how that would affect only two plugs. Did notice spark at the plugs not working when I held the wires close to the hole, so I have fire there. That is actually from the long stem that goes into the hole to the spark plug. The other two didn't spark there, but they seem to be the ones that are actually working. Thats about all the details I can think of right now. Any advise would be appreciated. By the way, it's a 1992 accord 2.2 4 cylinder coupe. I need to get this running right because I hate driving my 2004 v6 6 speed coupe
