The defect is in the alignment of the truck and the engine. With the alignment set to manufacturer's specifications the truck still pulls out of the driving lane. Within ten seconds the truck will completely vacate the lane. The second problem is the engine has a "stumble" or miss-fire at idle. Again the manufactures states the engine is also within guidelines. The dealer claims there is an industry standard for alignment, but provides no written documentation on what the standards are or what the manufacturer's acceptable tolerances are specifically. Do you have anything which indicates alignment standards and engine timing.
