About 1-2 months ago i was experiencing a misfire that i couldn't really diagnose, so i got a Delteq setup, problem solved. Now, I'm experiencing a ridiculously BAD misfire and I can't figure out why its doing this. Again, this is a recently installed Delteq setup which worked fine for the first 1,000 miles or so, and these are brand new spark plugs CORRECTLY gapped at .050 .... I'm just wondering what this could be? Could it be the Optical sensor in the Optispark itself? Could it be another sensor somewhere?

Is there any way i can diagnose this if it is indeed the optispark?

Any input is much appreciated...

thanks!

Possible you have a bad plug or wire.

Are you sure it's a misfire and not a bad injector? If not, I'd suspect a wire.

I once had a BAD misfire.... so i thought it was the opti.... ordered a new one, put it on and it got rid of the misfire, for like a week..... Then the misfire came back. Since the wires and plugs were new i thought nothing about them......... After checking all the wires and making sure they were not burnt and connected to the right plug...... I decided to change plugs for the hell of it..... I ended up finding a cracked plug!!!!! It was an NGK TR55..... NO PROBLEMS since then.... that was like 10K miles ago......
