Fuel Injection problems of the 2001 Mercury Grand Marquis

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.
