If it is not an ignition coil problem what other problems can cause something like this?
I heard of old transmission fluid to cause something like this. My trans fluid is clean but there maybe a chance it could be stail and not sufficent enough for the tans. anymore.
A friend of mine was telling me he had a similar issue with a ford winstar he used to have and the problem kept getting worse and worse and he suddenly lost his transmission. Basically because when ford put it on the computer they never found any codes and never experienced the problem when they test drove it.
As in the over drive light?
Does the check engine light flash when you have a bad fuel pump?
(mine flashes until i slow down to 100 and stay at a steady speed and flashes when I accelerate or go up a hill)
Is there only one ignition coil? or 8 for 8 cylinders?
Im guessing plugs wouldnt cause this problem or you would have told me already...lol hopefully
