Over the last few days i find that every time i change gears as i release the clutch the car hesitates a bit before it gets going again. This is very, very slight but enough for me to notice.

I am going to change plugs first as i have a set in the garage but maybe someone on here has had the same problem and can shed some light.

Car in question is a 2005 STi UK Prodrive pack running 333bhp, everything standard.

 

not happened to anyone?

 

Neutral Position Switch ?

dunx

P.S. Is it feeling a bit flat on boost as well ? Doesn't throw a CEL usually.

 

I had my neutral position switch replaced twice, I think this only really affects the vvt and wouldn't cause it to stall.

Have you checked the idle control valve?

 

Will check both Idle control valve and NPS. Cheers. Power still feels good but there is just something not right with her. I would like to get to the bottom of this as i have a MD321H to fit and would hate to have the mapper return again due to some fault we can not fix on the day.
