Coil Pack Problems??
I'm running a MY94 STi which under high boost whilst accelorating hard I experience pops and splutters, sometimes complete engine cuts. This does not happen whilst driving the car normally, which the car drives sweet as a nut, but seems to be an Intermitent problem. Would the problem be due to coil pack failure? The engine check light sometimes flickers, and can stay on for a second or two, would this happen If It were a coil pack problem?

These symptoms are normally associated with failing coilpacks but can also be caused by overboost/boost cut.
Do you have a boost gauge fitted - if so what boost do you see? What mods has the car had fitted? Cheers |
It would also be a good idea to check what code is being registered as the CEL lamp is indicating a fault ;) If you look HERE the diagnostic procedure is shown ;)

Are you running a fuel cut defencer or a chip in the ECU? as 1.2bar(17.40psig) is above the limit of the standard map sensor which is 17.2psig (1.185bar) so it is likely that you are initiating the fuel cut/boost cut.
