Help, Rb26 Sounds Like A Wrx

Wouldn't surprise me if its an afm. Another quick thing to do would be check over all of the I/C piping and joiners for a leak and vacuum lines too

My guess is afm or boost leak too.

I already replaced all those but I have it booked in at proximity motorsport here in mackay next Thursday. Hopefully it's nothing serious

The point is to find out what the problem is - otherwise you might as well get a new engine or buy a new car. You can't fix it if you don't figure out what "it" is first.

1 - find out which cylinder isn't running

unplug one coil pack at a time. if it runs worse, that cylinder is firing. if no change, bingo.

2 - find out why cylinder isn't firing

check plug, coil pack, loom, catastrophically low compression, etc.

That was already suggested.
