The affeced engine is the 4. 6l engine with the defective plastic intake manifold part number f8az-9424- installed in 1996 and up all crown vics,grand marquis and town cars. This is a very serious safety issue. Consider a family of 6 traveling an interstate, at highway speeds, when the defective intake manifold gives out and a rapid loss of coolant occurs. The driver panics and tries to get to the right shoulder, only to be hit by an 18-wheeler. Or the driver gets to the right shoulder and a highway patrolman stops to render assistance and eventually, a tow truck shows up to tow the vehicle. All these people are in harms way, because the defective intake manifold was not put on the recall list. Do we have to wait for people to die or are seriously injured, before the Ford motor company will finally extend their recall notice, from certain Ford crown victorias to all vehicles having this defective intake manifold? the driving public needs your help in getting the Ford motor company to extend their recall notice to include all Ford products having this defective intake manifold.

Car would not idle after starting. Thank god it happened in driveway. Towed to dealer, and dealer replaced iac valve, and cleaned fuel system. Car had 37974 miles on it. Purchased used on 07/03/03, was certified as used car, 33750 miles. Noticed intermittent turn signal flashing when purchased. Changed bulbs, no improvement. Shouldn't a safety recall be issued instead of a TSB on the idle problem?.

For about a month, been having problems with 2001 Mercury marquis. It would start, die, start die, etc. The problem became worst and I took it for service. Was told that the fuel injectors were dirty and that the injector motor was not working correctly. That the fuel injector should have been cleaned at 30,000 miles. I said that it was not listed in my service manual. The service manager knew that but again stated that it should have been done at 30,000 miles. About 15 minues later anotehr Mercury marquis came in with the same problem. The next day at work I learned that a friend was having the same problem with her Mercury marquis. So did Ford forget to list fuel injector cleaning in the service manual? dt.
