Technical 1.2 Running badly

[GrandeBenj]

Hi there, im having problems with my gp, the engine itself sounds louder than it previously did like a meatier sound out the exhaust, when i accelerate then lift my foot off the pedal the engine shudders, i had a service carried out 2 weeks ago and it was ok for a few days then started back with the problems, anyone have any suggestions.

What kind of service did you have?Belts?Just oil change?Spark plugs?

 

[GrandeBenj]

plugs, oil filter oil and air filter changed also both breather hoses.

Are the plugs the proper ones?check the oil level as well just for a start.

Check if the airfilter box is properly fitted to the throttle body...
