boost is crap... any ideas?

[fdavel75@hotmai]

hello people. this is my first post so id be very greatfull of any advice anyone could offer me.
a couple of months ago i purchased a seat ibiza cupra. very nice and rapid. it went fine for a couple of weeks then traction control and abs lights came on and wont go off... ive changed and uprated my pads and disks but still no difference.
2. when i put the foot on the floor the car has started jerking just before boost and during boos period. and some times theres no boost at all. this is really starting to annoy me . ive changed most vacuum pipes and cant see anything obvious. my cars been chipped and was starting to think if that would affect it in anyway. would performance spark plugs help??? im totally lost so any info would be great. cheers.

Please search.


And to answer your problem. Its your MAF (air mass sensor). Unplug it and see how it feels, if its better go get a new one on exchange.

yep its your MAF i had exactly the same problem with my car

Traction Control and ABS light on normally means you need a new ABS sensor !! Get someone with Vagcom to determine which one it is !!

ABS light 9/10 means a ****ed MAF.

 

[fdavel75@hotmai]

so if the maf is unplugged should the lights go of or will they stay on cos gettin no signal from maf? should i reset my ecu? cheers

they'll stay on until cleared now although occasionally lights will go out by themselves once the problem has been rectified

but with a faulty maf or no connected maf the lights will remain on even if you cleared them
