My car runs rough when i start it and it doesn’t matter if the engine is cold or warm. Then all of a sudden it just takes off ( like it kicked in overdrive and throws your head back) and runs perfect. When the car is running rough the ac does not work and then when the car starts running good ( takes off ) and this happens at 35mph-60mph the ac starts to work, and then when it starts to run bad again the ac stops until the engine runs better. Can you help me? Thank you Greg from Brunswick Ohio 2000 ford windstar 3.8
I am guessing a vacuum problem. Check all the hoses, look for loose connections or splits. Hopefully you can find a map all all those vacuum hoses.
