Hey again,

My Aveo - 2004 LS Manual, 134XXX KM, I have it parked while I troubleshoot a P0300.

A friend lent me a bluetooth OBD2 interface dongle, and I've been goofing around with Torque and my android tablet. You have to turn on some extra PID's but for $5 it's been very informative.

So far in order to correct the issue I have replaced the valve cover gasket, the plugs, and the wires.

YES it really needed to done. The wires I pulled out were covered in oil.

Yet the problem persists. What would have caused the gasket to fail in the first place? It's a common problem, I'm sure people have looked into that already.

[LETS do some research, then replace this line with some relevant data]

Anyhow, according to Torque - Cylinder 2 and 3 are misfiring badly. Misfire history is very high, and I didn't collect get any misfires from 1 and 4 in my brief drive. Also the car only misfires under load. I can't get it to misfire on idle - no matter how hard I rev this thing. I think if this was a coil it would be equally bad at idle.

There is also a relationship where 2 and 3 misfire right after each other, when they misfire, but the occurrence is random to me as of yet.

I think tomorrow, I need to pull the plugs from two and three and check on that gasket.
