Cold weather = higher air density = just reaching mass air flow sensing.

bet you live in a cold area...

the temp here has only dropped to 20-18 deg so i wouldn't think its much colder than when i use to go out at night in the summer.

How can i tell if its missing.

I have yet to check my plugs and coils and leaks so ill do that very soon.

I have done a bit of limiter bashing so my plugs my be looking a bit sad

replace your plugs to .08 gap . check coil packs . happens in cold weather change as said

Yea my plugs where always at .8mm but as said they could be buggered.

any opinions on new plugs i am using at the moment NGK iridiums at .8mm gap

whats a better choice for my car

You say boost cut, I'm assuming you really mean Fuel cut.

So your on boost then all of a sudden the car stops accelerating like you've flicked the key to off. So not popping and not missing.

You take your foot off the accel then put your foot back on and it starts driving as per normal.

Is that what you are referring to?

Thanks guys i have just cleaned and re-gapped my plugs to .8mm

and checked for cracks and burn marks on the coils and all seems to be ok

the prob has now gone with the re-gapped and cleaned plugs so prob is fixed short term.

so looks like ill get some new plugs and look into some spitfires for the long run

Thanks for ya help
