Exhaust Problem??

[paul6]

Hi guys, yesterday took the 172 out and i noticed a sudden change in note, its quite loud as it is, but it changed to a 'subaru' rough sound, and the engine management light was flickering.
Just started it again now, the light is staying off, but the exhaust is 'bouncing' around at the tailpipe end. Cant get under it to have a look yet, anyone have any ideas as to what this may be?

Also the car is de-catted.

Cheers, Paul

Whip the inlet off first, pull the plugs out make sure they're nice and dry and not nackered. If thats fine try a spare coilpack as they are known to fail. If its not that its the leads
