Flieger: You are confusing the SAI CEL with the Misfire CEL.

Here's a general list of misfire causes:

Non OEM Fan belt
O2 Sensor, Wiring
Vacuum Leak
MAF dirty
Dirty Injectors
Ignition: Wires/Caps/Rotors/Plugs worn
Various Hall sensor issues
Failing Dual Mass Flywheel
and rarely, wearing valve guides.

I might suspect anti-sieze causing an ignition problem.

Does your engine idle rough when warm or are you just throwing the code?
