WTF happened?

So I was driving my car around tonight... everything was cool, messing with the manual boost controller I have trying to set it around 12psi. Well, all of a sudden, my car sounded like a WRX and felt like it was on 3 cylinders. Now, this happened about a month ago too out of nowhere. I just shut the car off, unplugged the negative terminal to reset the ECU, and then all is good again. I tried just shutting her down and starting back up, but that didn't do it. I am running very rich (10.0:1 AFR under boost). You think one of the cylinders could have flooded causing no spark or something? Or even worse, ANOTHER bad ignitor? Any ideas?

Could just be a bad coil, they tend to start acting up once they get warm if they are going bad. Take it for a drive untill it starts soing it again then unplug a coil pack one at a time , the one that doesnt make it run even worse than 3 cylinders is the bad one.

I would try to do some tuning with that AFR you are going to foul plugs pretty quick.

sounds you got a bad coil or ignitor.

Good luck,

start it and pull off each of the coil connecters one by one until one of them doesnt have any effect on how it runs ( if it is a bad coil) then replace it with one from a differnt cylinder, if it still misses then its most likely your ignitor.

Hey Rafi, check your email...

Definitely ignitor issues.
