My XE nova was running fine, its been on the road for about 3 weeks. In the last couple of days its started to pop and crackle as you decelerate, it has also gone a bit flat.
Could anyone shed some light on why it might be doing this???

It could probably do with plugs, rotor arm, dizzy caps and leads. Not sure if this could be the reason.

help please :confused:

Mine does that, but I think thats due to low exhaust back pressure (no centre box).

Pops and bangs in exhaust are usually a sign of unburnt fuel making its way into the hot exhaust. Have you had the plugs off and checked their condition?

Hmm, do you have a lambda sensor?

Could be overfuelling, AFM gone duff.

Could be an air leak somewhere too

As above, could be an air leak. Check the pipe from the sfi box to the AFM for spilts/cracks :thumb:
