after driving afew minutes,doing 50mph with throtle barely open has flat spot, give it a little more gas, it goes away! used to spin tires from dead start, dosent now! seems like it dosent fire on all six. cam sensor was replaced,didnt fix it. was re scanned,crank sensor reading, will replacement of crank sensor cure intermitent problem? thought crank sensor was eighter run or no run issue! what about pick up vanes behind pulley ? does 4.0 motor have that set up and if dirty or bent would it make a difference? Mahalo! ken
