i was driving on hwy 243 this weekend and it was snowing a lot. 30 miles after i got down from the mountain the temperature was getting a lil warm and i noticed that my car was misfiring when accelerating. it happened a couple times and after that it was running fine. i read somewhere in the forums that it is normal when you have drastic weather or temperature changes. is this correct? has anyone else experienced the same thing? car has 33K and i havent done my spark plugs. any help would be appreciated. thanks

 

Yea your ecu has to make adjustments when temperature and atmospheric pressure change so I can see that happening. Changing your plugs wouldn't be a bad idea either.
