You must have been saving the letters T and H for your name...!!!

Don't count out the AFM if it was a second hand one you put in. Some could be faulty.
Sounds like you might be down a few coils on the passenger side. If it is running the same without them, she's down two cylinders. Try replace them first and see how you get on.

defo not head gasket

sounds like coils on passenger side
[/quote]i hope ur rite duffman i only put a new box in last week.... but i hav 4 spare coils and i tried all of dem to no avail my head is wrecked... its been sittin up all nite and i went ta start it der and its strugglin ta start and wen it does it just cuts out..?????
 
check the plugs aswell, i had a cracked plug a few months back and it caused a serious misfire and caused the engine to cut out.....
 
I could just be your spark plugs!!
Sure throw in a fresh set and you'll never have to do it again
I imagen the two in the cylinders that aren't working are screwed now anyway!
I hope you get sorted soon, I'd say one of our tech heads will be on shortly to give his opinion!

Regarding the text talk, Most of us can't read it! :thumbsup:

Thanks for the heads up Dan I only put pfr7b's in it not too long ago would it be regular that 2 plugs would go at the same time on the same side???? Thanks for all your help so far lads
 
on the passenger side some times the plugs are tightend to tight as theres a bit more room to get to them, i had the same problem before and the two plugs on that side had cracks in them.

if you had of said at the start you only changed the plugs i would have taught of that.

i'm sure its either one
 
when i say i changed dem it might have been christmas wen i did them they should last longer going by my experience with subarus but then again stranger things are known to happen i suppose... i have a friend coming down with a compression tester at 8 please go its good news thanks DUFFMAN :thumbsup:
 
Oh Jaysus!
Sorry man!!
That sucks ass
Is it worth getting a second opinion? you might save your self a load of hassle!
Build her bigger and better, :thumbsup:
