Hi all.
I've been experiencing a lack of acceleration that's noticeable around 60mph. For example, in 4th at 55-60mph, plant foot down, starts accelerating and then all of a sudden it stops? Then take foot off accelerator and re-apply and then starts accelerating again?
It seems ok with town driving, and speeds up to 40mph; pulls like a train. It's only noticeable at the higher speeds.
What could cause this? I'm assuming it's a boost problem.
On another note: I started the car and pulled the MAF plug out - no change in performance (except the ASR light came on the dash). There's no lumpy idling, no limp mode and no black exhaust smoke.
I'm also getting average 40mpg combined which is pretty good, and no noticeable increase in fuel consumption from previously.
Any ideas? I'm a bit lost!!
