hesitating at first startup
My 2000 Max hesitated bad this morning and was knocking. Just got the car a few weeks ago and noticed it hesitating a little when first starting in the morning but thought little of it until today. It also knocks a little when first starting it up, any ideas whats going on here? it has 160k miles on it and otherwise runs damn good. Maybe plugs? knock sensor?
Thanks,

i'm tempted to not help since you have the verboten word "Jetta" in your username, but I'm in a good mood:
three things:
First: Change spark plugs at that mileage.
Second: Clean the throttle body...this will eliminate most hesitation problems. At 160K it must be dirty as hell...mine is grimy after every 10K miles.
Third: If still hesitating, replace (or clean) the MAF.
and there's always Seafoam!

Well, I cleaned the throttlebody yesterday and also changed the plugs. It does run smoother, however now after paying much closer attention to the engine I noticed it does have a slight, steady knocking. MAF sensor?

Did you check the oil level? Has it been changed recently??
Mine also has a relatively quiet knock at idle. Sounds like a soft rod knock. Just chalked it up to no big deal since it's way quittier than the lifters in my last car.
