Rb20Det Cefiro Engine Issues, Help Please!

Hi guys, today i was driving on the motorway and out of nowhere my ceffy starts sounding like a wrx?! i was like 1km away from the inlaws so i practically rolled to their place. It would run smoothly then start misssing on and off. So i left it for a while and a couple of hours later started it and it ran fine, so i took it for a drive round the block but it seems way down on power. Any help or ideas would be great as i have to drive 2hrs home tommorow. thanks

Coilpack ignitor or CAS, when playing up will work perfectly fine when cold but can cause misfires when they heat up

thanks i will have a look, would this cause it to be so down on power? its weird because its never done anything like this before. Also the catch can seems to have filled up fairly fast since the last time i checked.

Had a look at CAS and ignitor pack, from the outside the look fine. CAS hasnt moved, ignitor pack and plug look ok. could it be a coil pack or spark plug?

plugs fouling up / coil pack , if it sounds like a wrx its running on 5 cyl .

maybe remove coil pack cover so they dont over heat

i'll check the plugs, does it seem strange that it sounds like its running fine but is way down on power? it isnt doing a wrx impression anymore, but is real slow.

Turned out to be a combination of things, igniter pack plugs were corroded, the connection between coil pack and the top of the spark plugs had been arcing badly and also a coil pack has shit itself. Thanks for the help guys
