Misfire-engine light

My barchetta, misfires, and engine light comes up.
until now, we have checked:

-Ignition coils/spark plugs/wiring
-fuel pressure
-Cylinder pressure.
-cleaned throttle body, MAF.

whats next on the list? (could it be engine management?)

Re: Misfire-engine light

-changed temp sensor.
but can a bad lambda cause misfire? (if it misfuction it would send rich mixture, i think)


waiting for the electrician next week to check the engine management module, if gone bad.
