Only had my Scooby for one week so everything is new. I need some advice.
From cold the first 5 to mins of driving at a cruising speed like 45mph it feels like the car is slightly pulling then smooth then pulling. A slight judder feeling but when its warm it goes away. I'm not explaining it right, I can feel like the turbo wants to cut in but I'm not letting it, is this normal?

Thanks for the help

 

MIne does the same dont worry about it

 

It's just the lambda sensor not being hot enough - the ECU switches to closed loop (using the lambda sensor for fuelling estimates) before it's hot; this leads the ECU to underfuel a little, so as it tries to fluctuate around stoichometric (14.7:1AFR) for which the lambda is feeding it the wrong info, you feel the car feeling being ok/not ok, which can lead to juddering when it's lean.
There's only 2 ways I can think of to get round it (other than just putting up with it!), which is leaving the probe to warm up before driving (it's self-heating, I think!), or changing the ECU to one which doesn't run closed-loop, which is a tad expensive if that's all it's for

 

I'm glad its not a huge problem. It only does it very slightly, not even passengers can feel it. Thanks for your help guys.
