Hi,

I've recently noticed a slight mis-fire or hesitation when driving under low revs. Not so noticeable when under load and the car still seems to be running well.

It's a MY00 classic, has had TEK3 remap and the slight hesitation seems to occur whether cold or hot.

Any ideas what I should check first ?

Maf sensor would be first IMO...

 

My standard my99 is doing something very similar. Going to try the 'earthing mod', do a search on here, there's loads about it.
