I am trying to figure out the problems with my 2002 ford windstar van. here is the first scenario --- cold -- first run of the day -- when you start it idles extremely high... 3000 rpm for quite a while then idles down. when you put into -R- it really wants to go and in a hurry...idles up and takes off. second scenario -- if you are in a line up - drive through --- idleing while in -D- then take your foot off the brake to move foreward.. it really wants to go.. you put your foot back on the brake and it is really pulling against it.. like it is possessed and want to drive right into the car in front if im not awake it can catch you by surprise. third scenario --- backing out of a parking stall at a mall or store etc etc.. slowly backing out and turning with foot on the brake... wants again to go! but if you hold your foot on the brake long enough.. it will stall out.
I have taken it to the shop and no codes found on the engine tester and we replaced the Throttle position sensor yesterday hoping this was the issue but nothing has changed. reacting the same.
PLease if anyone can help me out I will really appreciate it.. before I spend hundreds of dollars replacing unesscessary parts.
Thanks for yout time.
