Can Anyone Help
 

Iam new to this and to scobbies too so here goes.
I have a 1994 impresza wrx but she is not very well.
She was running fine when i parked her up but when my wife went to go to work that evening the car had cooled down by this time she had produced a misfire anything above 2500rpm (the car not the Wife lol)
It has an f c command stand alone ecu and a decat 3.5 inch exhaust.
I have changed the plugs and coil packs (expensive or what) but this did not cure the problem.
Does anyone have advice.

Unusual.. anyway the commander has been altered by accident?

Maybe time to let someone look at the map on it / diagnose the issue.

Thr powerfc doesn't worry about things that on the standard ecu could cause a misfire or cut etc.. so most likely fuelling or spark related, so the plugs and coils a good call.
