I recently stored my car for several months and prior to this I added a fuel preservative to the tank. I now must operate the emergency switch to shut off the engine. Will this problem correct itself after the fuel additive is out of the system or do I have a problem that requires servicing? I have read somewhat about this problem and wonder whether I may have a vacuum problem with the shut off valve. If so where is the valve located and is it easy to check? Door locks operate OK. What might be a ballmark cost for the dealer to repair?
Thanks
