OK guys... newbie here from Texas. My son's newly purchsed van has the exact sme problems here. If the problem turns out to be the computer, where would I locate it for 'warming up' or replacing it? I am a X-ASE master tech (foriegn BMW / Mazda / Subaru) from the late 80's-early 90's. Needless to say the electronics have changed some and I have gotten a little rusty on my diagnosis of cars having been out of the loop for many years now. Appreciate these forums from what I have learned to assist me on all of my automotive problems. So prematuraly I would like to thank you for your help in this matter.
