Re: 1999 ford windstar mini van jerking
This could be anything from bad plugs, bad gaskets, low fluid on the trans, needing a tune, etc. Do you happen to have any more details?
Does it stall out?
Does it over heat?
Do you have issues starting?
Are you running through more gas than usual?
Does it stumble only after running for some time?
There are more questions, but this is all I could think of off the top of my head right now. Any more info you can provide would be helpful as those of us on here can not be right there to help diagnose/Troubleshoot the problem.
