first off i have searched the forums and have found no thread like this lol. So ihav a 1993 mark viii with 200,000 km on it with all scheduled maintenance done and a recent tune up ( plugs wires filter oil etc...) The other day i was stopped at a traf light and the car started lurching so i popped it into neutral, the car was still revving up to about 1800 rpm then would drop then rev again then drop then rev the drop etc... As it was revving up the chek eng light would come on then turn off as it dropped down, as it was dropping dow the overdrive off light would come on. The car kept doing this until the light went green and i was able to pull it over. I turned it off. I waited a few mins and started it again. It still was running rough but without the chek light and the revving, So i turned it off again and waited some more. I started it again and it ran beautifully?? I was headed to the airport to pik my fiancee up so i had to continue on. A few km later the chek eng light came on and the car wouldnt shift into over drive and the push buttom on the shifter wouldnt even turn the light on the dash on. I left the car. Wen i returnd i had a code reader and did a engn on test and a key on test. The car held no codes??? wtf. The problem hasnt happnd since and the car has been running fine. Any ideas? stumped!
