Can anyone help?
My version 5 STI starts and runs fine. When I accelerate from cold its fine.
However, when it gets slightly warm it thinks for a second or so before it goes. I have no engine management light on so suspect its not the MAF.
I have just had the car serviced and all filters changed, plugs etc. also just been stung £80 for some magnacore 8.5mm leads.
Next step must be the coil pack but don't want to spend anymore dosh.
Does anyone know what the resistance across the coils should be?
Its a diamond FH0161 12V
Cheers

 

sounds like a Maf problem to me. Had the same fault on my g/f's car and it was the Maf

 

I used to have trouble with the MAF until I changed out for a K&N induction kit, but when it failed I got the management light on. Not the case this time?
The car hasn't returned to a 'default' setting as previous.
