I have a 97 Civic with a Y7 block and a Y8 head. When I first start up the car, it idles fine but when I give it gas you can hear a misfire. When I'm cruiseing down the road and I barley give it any gas, it will run fine. But when I give it just alittle more gas, it will miss like crazy. The CEL will flash but as soon I as back off the gas, it will run fine but the CEL stay on. The only code Im gettin is for a misfire in cyl 2. I changed the plugs, wires, car rotor and I even tried the injector. It feels like im running out of gas but its only happening in one cyl. Any ideas?

 

Check the compression in all of the cylinders. Cyl 2 may be low.

 

would that cause it to happen only under load? After I've been drivin for awhile and I stop, it will misfire at idle then correctitself, run smooth, then miss again, and it will keep doing that until I take off again.

 

I finally found out what it was. It was the gap on my plugs. I regapped my plug and it stopped the misfire, i then regapped all the other ones and now the car feels like it has alot more power. Something simple as a plug gap made my car run like crap.
