Title: Deceleration?
Post by: Dougie_91 8v GTi on 17 June 2007, 22:58

I let off the accelerator, even going down hills and the car slows quickly, not as much on steep hills, but you can do 25-30mph on a fair hill in fifth and it will not increase in speed much unless you poke the throttle!

I guess it may be a fuel/air mix problem, the exhaust does blow slightly, is very loud when decelarating and does pop occasionally from the rear, although Kwik Fit could find much wrong on Saturday, and there has been a drop in the power/accelaration since I bought her 8 weeks ago.

All I have had done so far is change the middle boxes on the exhaust? Apart from drilling holes in the airbox which I'd rather not do as I'd like to keep the car fairly standard what can I do? :undecided:

I'm not sure if i have understood you correctly but that sounds normal.  I am assuming you are talking about doing this while the car is still in gear?

In gear i would expect it to slow rapidly and in neutral it should just carry on rolling.

popping on a digifant can be caused by the ignition timing being set incorretly, check my digifant tuning guide :)

also check your vacuum pipes for splits, including the oil breather bung thing on top of the rocker cover (the "flying saucer" thing sits in it). Mine split in two causing a vacuum leak, causing lots of popping and a loud exhaust  :laugh:

not to mention a buggered idle.
