jtbel Posted October 14, 2006 Share Posted October 14, 2006 Hello, my car starting running rough and I got a cel. I got the code read as random misfire (did not write down the code numbers). I had washed the engine a day or two before, so I figured it was related. I had not changed plugs or wires in the 2 years that i've owned the car, so I replaced the plugs with no change. (There was signs of corrosion in a few of the spark plug tubes). Then I replaced the wires and that seemed to fix the problem. After a couple of days of driving fine, it starting running rough again, but not as bad as the first time. I got the code read as a misfire in cylinder 4. I have the plugs gapped at around .43, and I rechecked all the wires. Also, I put in new rotors and cleaned up the caps. Has this been a problem for anyone? Any suggestions?

LScott400 Posted October 14, 2006 Share Posted October 14, 2006 Having done plugs, wires and rotors I would recommend you change those 12 year old coils. Quote Link to comment Share on other sites More sharing options...
jtbel Posted October 14, 2006 Author Share Posted October 14, 2006 Hello, I'm not sure why my signature says '95, i'ts a '97. When the code said random misfire I figured it might be a coil or a cap, but when the second code showed just one cylinder misfiring I figured it might be just a wire or a plug. The resistance for the passenger side coil was within spec, the driver side was not as accessible. Anyway, I had the right side cover off in preparation to check for spark at night, but was too tired last night. This morning I took the driver side cover off and the idle smoothed out. I don't know, but maybe one of the wires was arcing with the cover on and stopped when I took it off. I knew it had to be pertaining to the wires because it was working fine for a couple of days after I put them on. Whew! I just barely avoided taking it somewhere.

jtbel Posted October 14, 2006 Author Share Posted October 14, 2006 Okay, now I know for sure what the problem was. One of the plug wires had a cut in the rubber. I'm guessing it must have gotten cut when I put the cover over the wires. I could hear a clicking sound coming from that area and it was contacting the engine. I taped it up and made sure it was not touching the engine and i'ts good to go. Quote Link to comment Share on other sites More sharing options...
