I have a slight miss at mid to heavy load around 1500 rpm. It seemed to be there before I added my 370s. It is slight, not near as bad as a lose line. Also In the morning when it is 50 60 out I have to let it warm up for a minute or so. If not it idles fine but will shakes when put in gear. There are 208k on it now. It was stock till 150k. I am thinking dvs or p7100. Any ideas?
