That was around 2012 new year time when I , my wife and my kid visited our friend at atlanta, GA. We drove our van on interstate highway I-75, in the middle of our trip, our van started shaking vigorously. I felt that was from engine, it forced me to stop on the side of I-75. After a while we restarted our van, we could only drive for < 65 miles/hour. Any acceleration resulted in vigorous shaking. After we came home I drove my van to an auto service center, and was checked. It turned out that 3 ignition coils, spark plugs, and manifold gasket had to be replaced. Yesterday (9/10/2015) the same problem happened again.

August 2003: check engine light comes on. Vehicle taken to crystal motors, a Toyota dealership. Crystal motors replaced "ignition coil". Problem apparently resolved. Cost: $350-$500. January 2005: check engine light comes on again. Vehicle taken to crystal motors. Replaced "all injectors and coils". All six fuel injectors and three coils were supposedly replaced, according to the technician. Problem apparently solved. The service cost approximately $2100. July 2005: check engine light comes on again. Crystal claims that a coil has gone bad, only 6 months into its use. Crystal is unable to produce the defective part on demand. I was not charged for this service.
