Problem when decelerating

[Drayvn]

I was just noticing that whenever i let of the gas pedal, the car will shudder slightly and sluggishly, if you get what i am saying, but it only happens when i decelerate, everything else is fine, does this mean the engine insides and exhausts need a good clean out???

If the problem is on overrun (when you lift off) try get your timing checked as it sounds as if your not firing properly, alternatively check plugs, leads, dizzy cap and rotor arm....

Should resolve the problem...

If you've put an aftermarket turbo on the car check the wastegate.
