Hi, When im driving it feels like the hand brake is partially on, its only when im in 2nd are 3rd and push the accelerator peddle to the floor and it gets very high revs.Then it picks up and drives perfect,like it used to do. What can cause this... 06 scudo sx dynamic jtd

I have the same issue. The turbo doesn't kick in until late.

I believe JohnDragonMan said a while back, it's related to i think, the Throttle Position Sensor, which is a box located somewhere in the top left of the engine compartment (drivers side, above the engine). I haven't done mine so far, but it's on the to do list. After you adjust it, the turbo should kick in at lower rpm's so you get instant or near instant boost.

I'm sure someone will confirm this. It was mentioned a year or so back, so my recollection is hazy. wink

So I got off my lazy ass and looked it up.

oh.. dont forget to adjust your throttle cable.. under the bonnet, under the wiper motor you will see the throttle position sensor.. the throttle cable on that has like a peg on it. make sure to pull the cable out just before the TPS starts to move and replace the peg. may aswell recover the 100% throttle movement!

Hi, well i disconnected the Mass airflow sensor and all is good she runs like she should, there is still a slight delay before the Turbo kicks in but im happy with how it runs now.

When I broke my MAF with a fat finger poking where it shouldn't I had similar symptoms.

I'd start off slow and without increasing pressure on the accelerator pedal much, all of a sudden it would find it's wind and start accelerating as if I was slamming my foot down. A new MAF fixed mine but it was the obvious thing as I was there when it broke lol
