08 nissan sentra bucks during snow storm
Maintenance/Repairs nissan sentra
Hey everyone I drive a 2008 nissan sentra(98xxxmiles). I commute 100 miles daily and have an issue that occurs only when it is snowing. Regardless of how much snow is on the ground, every time there is decent snow fall my car will randomly buck. feels almost as though my transmission slips for just an instant and then regains control. for a while, i had to study this issue before i could fully wrap my head around it. I took the car to my shop and they could detect nothing wrong with the car, which is definitely not the case.
i suspect that there is an issue with a sensor or an actuator involved with the overdrive that is having the issue. but i could be wrong. does anyone having any thoughts or knowledge such a sporadic problem
Explorer 2000 engine bucking in snow

This car runs fine, except when it snows. Then it starts bucking like the engine has quit and restarted. Rain does not cause this, wind has no effect. Even if I start out with no snow in the air it runs fine (and regardless of the temperature outside), but if ONE snow flake happens to drop off of a tree in its path then the fun begins! It doesn't seem to matter if it's a nor'easter, or just a few flakes. My mechanic has no idea, and the Ford service guy at the dealership has never heard of this. ANY IDEAS!!? HELP!!!!
I lost hope until I did some more googling and other people who had the same problem replaced their air filters. Air filters not seated properly or defective ones allows snow, dirt, debris, etc... to pass through and hit the MAF sensor which sent a current spike to the ECU which made it think it sucked in a huge amount of air which would cause the engine to compensate and by giving less fuel and then end up with a misfire but no code because it was compensating for the "amount of air" which was actually a snow flake.
I decided to try it and IT WORKED!!!! WHOOHOOOO!!! When I took out my old air filter, it turns out it had a faulty seal (seals were worn and destroyed) which caused the snowflakes to enter whenever it snowed! My car drove like a beast last night in the snow and no bucking of the engine yet! Luckily, it snowed enough last night and the road conditions would have definitely caused the engine bucking but it didn't after replacement! So, I'm confident it's fixed from what I've seen last night, only time and more snow will tell but for now it seems to be fixed. It's only taken me two years to figure out what's going on with this problem. I will update if the problem comes back, hopefully it doesn't!
I will do a snow dance for you (to the untrained eye, it could be confused for a rain dance), to make sure you get a good thick amount accompanied by wind for testing purposes.
Thank you very much for the update, sincerely. It will sure help someone else either get to or eliminate possible causes faster.
