Technical Let's hope it's the coil packs!

Fault code came back U6100 which appears to be a key coding ref , cleared this , am assuming this is an old code , however no other codes showing , im hoping now that it's just the exhaust
 
Good luck.

Do you just have lumpy idle or does it affect engine when driving too?

The ECU isn't storing a misfire code. so if it is missing the number of misfires in sample period are not exceeding the acceptable number programmed into ECU.

Just rough idle , however when it accelerates it make a slight flutterng sound

Just uneven idle , however when it accelerates it make a slight flutterng sound , when we were kids we used to put playing cards between our bike wheels and the mudguard and as wheel passed it flickered , it's a similar sound to that , I've just read a similar thread where it turned out to be the ignition coil

Maybe the fluttering sound is your mystery pipe ?

If coil insulation breaks down and a spark is jumping from the coil to a ground point, the spark can make snapping noise .
But if this is happening the spark is very unlikely to occur at spark plug and so you would have misfiring.
 
Great news it's just idle , you can drive the car happily .
 
The mystery pipe is no longer such a mystery it's a rubber pipe that hangs vertically under the battery tray , don't know exactly what it's for , poss to get rid of rain water ?
 
Thanks for the update on rubber pipe .
People on the forum like to have answers as much as you .
Pipe incase battery leaks , so any acid leaked does not disolve your car .
