	could be, it's pishing down with rain and never stopped so not had anytime to check anything really :( hope it's something simple, mind you still under warranty for another 6 weeks or that...

	spark plug gaps not quite right?
mav	posted on 24th Oct 05 at 16:45
	any other opinions ??? car runs great...but still that slight 'pullback'.. need to get it out for a good blat...check hoses etc too i think...

I would be checking they actually changed plugs etc... Did warn you about them... lol cowboys....

	:lol: aye Marc....not the same kind of feeling at all... going to get my bro in law the mechanic to take it for a spin and see what he thinks... it's under warranty for another 5-6 weeks so if there is something needing done want to get it sorted ASAP..

	I was going to suggest it could just be a flat spot, but i thought you'd be used to that after driving the Vec.. :\|

	mmmm sounds like the ECU is retarding the ignition. does the boost drop? it could be the AFM (if it has one). are you running super/optimax.

	say i'm sitting in 3rd at 30-40 and plant foot, it takes off and noticeable 'pullback' sort of thing then goes again..... does it at high revs and low revs i think....does it uphill/downhill and on the flat..

	where abouts does it do it mav in relation to full boost. does it do it just on full throttle, does it do it downhill, high revs low revs. a turbo car will have lag before boost and when cruising as the turbo has to spool

	try the plugs and check for split hoses

	sounds a bit like a flat spot mine has developed one, hoping it clears when ive done plugs and leads if not then im gonna get it rolling road tuned and go from there with process of elimination
mav	posted on 23rd Oct 05 at 17:23
	maybe just turbo lag?? as i haven't drove a turbo before.. when i plant the old right foot, it flies then will stutter for a split 2nd before power kicking in again??? I'm a bit of a novice on the whole turbo side or things??? tried it in 2nd / 3rd and 4th etc and does the same, never noticed what revs are sitting at though when it occurs.. the thing is it is still flying though, feels fast but just the slight stutter annoys me ???? opinions and ideas peeps...:)
