every now and again when my99 is idling revs flutter +/- 100-200rpm. have fitted de-cat centre section & bb, bailey d/v and itg panel filter. panel filter has a tiny split in rubber, could this have any affect or is it the maf sensor on its way out? new to this scene so any advice appreciated.

CHEERS,

Could be your MAF sensor mate.

Does it try to cut out when your driveing and you pull up to a junction or sumthing??

ONLY EVERY NOW AND AGAIN IT WILL DROP DOWN THEN STRAIGHT BACK UP. IT DOESN'T DO IT ALL THE TIME JUST EVERY NOW AND AGAIN. ME THINKS WILL GET IT SORTED ON WARRANTY.

Yeh. Sounds like tour MAF sensor or your AIR IDDLE CONTROL SOLINOID.
Do a ECU diognostic test.
