Hi,

I can't see al the advice proferred here, but I seriously doubt that is a Sleeve issue. This is a non-issue on '99s (it's a '98 thing) and have never heard of this issue popping up on such a relatively high mileage car (62k+ mi.).

MAF is a possibility, especially when you add in the K & N variant. Just wait to see what the mechanic says. Good Luck!...

Happy Motoring!... Jim'99
