low compression
I have done a compression test on the ford windstar 3.8 engine and found that the engine
seems to be running rouqh becuase cylinder one has 90 lbs , cylinder two has 80 lbs ,
cylinder five has 70 lbs and cylinders 3,4,and 6 have 120+ lbs to 130 lbs .
would you say some thing is keeping the valve partialy open and a good engine flush
might do the trick .
