I've been experiencing major problems with my 00 maxima. The other day my car wouldn't start. I got a jump start from somebody as i drove away my car started to buck a little i made it to the highway and the car seemed to drive fine. when i exited the highway my car started to buck again and the dash comp. lights started flashing and i eventually stalled luckily i was on a hill and coasted down the hill (with no power anything) in to my fire station parking lot. Thinking that i had a bad battery i had it replaced and my alternator checked out fine. Today while driving home from work it stalled again and wouldn't turn back on. Again the dashboard lights flashing before stalling. I've read it may be the Mass Air Flow sensor. I'm looking for a point to start diagnosing
