So now and then not ALL the time when I'm in boost about peek boost, it will chug and fill like its cutting out. Also I'm THINKING I might be having a cam sensor going out because the tach is droping off and engine light has been coming on. Will a bad cam senser cause it to cut out. Also not sure when the fuel filter has been changed last. Not sure how pickey these cars are on low fuel but thats when I notice it. Other times it wont do it.
