when driving if i get on the throttle hard sometimes i lose power like a sensor kicks in or something anybody have this problem.

99% chance its your mass air flow sensor, if so you should get a check engine light soon. expensive part btw but very easy to replace if you buy it yourself

It could be your maf,not quite 99%,if it was failing flat line you would have the power loss but they are on such tight ranges that even slightly out of range you should get a cel triggered for the teltale p0170 and p0173 codes.
OBD2 scanner 94169 for 39 bucks at harborfreighttools.com or their store nearby if you have one.To read codes when you do have a cel on.And maf sensor insert for 127 bucks at germanstar.net bosch oem unit.
Clean your maf with crc brand maf cleaner and see if that helps.Under demand I would suspect a dirty fuel filter as another possible culprit,when was it changed?

could be a pedal value sensor also which senses the accelerator pedal
position. these do go bad and eventually the esp bas light will come on.
This doesnt always happen at full throttle but you can feel it when just pressing the gas and nothing happens. just another possibility!!!

yes tech u no the score with out dianostic its a mass sensor fault i would say 100% air mass

thanks guys for info ill check on this remedies cant have the loss of power thing

the only way i knew my shocks were bad was because of abnormal tire wear the ride is so good on the 320 u dont notice if ur shocks r bad whats a good replacement ( want sporty handling with out very harsh ride )i like kyb good shocks are the bilstein gas a better choice they are the same price .[&:]

Don't go with kyb they are not valved for the street and you won't like the ride.
