Open the full vehicle complaint log (all categories)Vehicle purchased new off the showroom floor with 22 miles, driven locally only and garage kept. At 270 miles, upon starting the vehicle the engine was shaking and idling rough exactly like a misfiring cylinder would. The check engine light immediately turned on and started flashing and the engined bogged down and stopped. The dealership towed it to their shop and witness the rough idle themselves. When diagnosing the fault, it was confirmed 3 cylinders were misfiring due to "catalytic converter sensor" that triggered the engine to misfire for "protection reasons". The dealership checked the distributor and spark plug wires with no issues found, ultimately they reset the code which immediately returned the engine to proper function and idling. They drove it for 60 miles confirming proper function. Their "theory" is possible bad gas could have been put in the engine prior to the dealership buying the vehicle?? We told the dealership that we have not even put gas in the vehicle ourselves yet thus no fault on us for this postulated issue.
