i have a 1999 dodge durango with the 5.2 i believe it is and it has developed a misfire. it is throwing a code that it is cylinder #4. it is getting spark and the plug isnt fowled or anything so i was just wondering what to check next and how to go about fixing it. speedy responses would be very much appreciated because my sister is taking this car to school in a few days and i need to have this fixed to get emissions tested. if you need more info i can try my best to fill you in more, but any input would be awesome! thank you so much!
