weather my friend as in ambient temps can make the tune change
also is the motor new maybe the plug is bad
more then likely the lsn is lean but as stated above try reading the tuning bible it has some really useful tips that may help u and u will learn a lot for them
P.S
wen at idle does it sound more like a machine gun tin tin sound then its lean
also is the motor new maybe the plug is bad
