Ignition Problems

[Red Sky II]

Been having an annoying problem with the Stagea (RB25DET Neo) in that the Engine Warning Light comes on intermittently usually accompanied by engine retardation.

The dealer's mechanic have been tyring to fix the problem for weeks now. It started after they replaced the coil packs and fixed a rough idling issue. Now I get the above warning light although car runs fine when the light isn't on. Stopping and restarting usually gets rid of the light and can proceed driving.

The last attempt at fixing it was to replace the Cam Sensor and change the timing. Worked fine for a few days but it is now back and it is becoming very annoying.

Searched the forums and found 1 post where it turned out to be loose wires.

Hoping someone has some ideas of where to look next to solve the problem as not enjoying the drive at the moment.

Any help would be appreciated.

Cheers, Al

Sounds kind of like a knock sensor going bad or maybe the plug is loose on one. Only because of the retardation, not sure if they trigger the engine light or not.
