This is a weird problem and thankfully doesn'the seem to be getting worse. When it's cold or just getting warm my 2002 Scudo 2.0jti runs like a dream with mid forty mig and easily achieves 7th. However once nice and warm she is fine so long as you don't change gear and have to accelerate. However in the real world of driving this doesn't happen. It brakes and slows down really well, the trouble is as you accelerate. As you push the pedal to the floor you can feel it struggling with a distinct lack of power with 40 as a top speed in 4th and not liking 5th. It really struggles up little hills. Keep the pedal down and you feel a power kick and she is fine until you next brake or slow down. Then after you slow and want to pick up speed again you get the lag and eventual power kick. There are no codes on my mates Snap-on diagnostic machine. Any thoughts? It had a brand new exhaust 6 months ago and the trouble started 3 months ago. Trouble is I am disabled and my Scudo has been converted to house my wheelchair and is my lifeline with the independence it offers me. Without it I am housebound which I find really depressing. I really hope someone can help and tell me what the problem is.
