Ok. 2 Days ago the car was running pretty well, I've been having a little problems with it, probably just reg. things though no biggy. But I went out there yesterday, in the 12 Degree weather, started my car, waited about 10mins tried to drive it and that thing hit like 1-2RPMS and shifted, then TOTALLY SKIPPED 2-3RPMS and went to 4RPM and just revved, not going any faster then 20MPH. Then when it did Shift it would JERK. All day yesterday, just doing that, so while online doin research I found a lot of people stating that the MAF is probably the culprit. Any Experienced Mechanics or Nissan Maxima pro's here that can help?
