The van starts to shake at higher speeds. You can press on gas and it shakes, let off and it quits. It seems to happen after it shifts into overdrive. It had a intake manifolded leak so that was fixed but did not help. We then replaced the computer chip and it did not help. The mechanic did a test drive and said when he touched the brake pedal it would not shake anymore. We are out of ideas
