Car constantly jerks and bucks while driving at speeds lower than 60 mph. At first it only bucked between 45 and 55mph, with jerking here and there. Now the problems evolved into a full on seizure at all speeds until about highway speeds. Sometimes the Check engine light flashes, but one things consistent...the jerking. Car runs like sh*t. Have no clue what it could be, last I checked the CEL it was just a coolant sensor. Wish I had the answer. Best I got is to scrap it, its probably the best thing you could do for your wallet
