for your mis-fire one thing I would check is your spark plugs. Last winter I was getting mis-fires and jerky when I accelerate. The gap on mine was about .060 in. Check the gap I believe it should be like .045 in. cause the stock plugs are not the best. They are rated at 25,000 miles. I put Autolite double platnim in my are and the problem was solved. The double platnum plugs are also rated at 100,00 miles. and for about 4.50 a piece not too bad, less than 20 bucks for 4.
