I have a 1993 honda civic le it was running fine and then it started too run like crap. While in idle i pulled the plug wires to check for spark and noticed no spark on Cilinder 2 while wire was pulled the car turned off and then wouldnt start. After that i had to replace the distributor because it wouldn't spark at all. I got it running but it still has the same problems. I've been told ours only running on 3cylinders. Its not the spark plugs or wires. Not the distributor. Any ideas what it could be?
