Ok, I was driving today and I got on it bringing the rpm's to 7k or so and then all of a sudden the car started running real nasty like it was only 3 cylinders or sounding like a v8.

I checked compression, wires, plugs, distributer, ext. coil and all seems fine. The cam gears line up still at TDC. Vacuum lines seem good. My fuel pressure gauge shows a steady flow. Im running a obd1 h22a in a 98 civic. Any suggestions, ideas, or opinions will help. Thanx

 

Check to see if all of your injectors are working

 

Check to see if there is spark in all 4 wires. With each wire, stick a screw driver in the boot and make contact with the metal in there. Then put the shaft of the screw driver close to a metal chasis point. Have somebody crank the motor and see if a spark jumps. If and when you find one wire thats spark doesnt jump, you've got the problem narrowed down alot.

 

Thanx guys, it actually turned out to be an injector thanx to a wire on the resistor box.
