Q&A

Thanks for the info....I'll keep that in mind. I have found that mine likes to crank w/o a start as well...the best solution for mine has been the throttle position sensor (tps). When I remove my TPS connector & re-install it...the car starts immediately. Sometime for only that one starting sequence...then I have to repeat the disconnect process again. Bummer... Now it start every time but has the engine racing @ high idle speeds whenever the gear is in Park or N...

I am ready to do some digital multimeter testing of the TPS as the winter weather is giving me a break...finally. From the Haynes repair manual...it appears that the TPS is malfunctioning or doesn't know where the 'zero' point is (start...low idle).

I will be pulling the KOKE self-test as well...

Thanks again for your determination for 4 years...wow !!!

Also ran across this in the Haynes repair manual & while doing a parts seach...related to my high idle speeds...in Park or N..."idle air control valve"...!!!

IDLE AIR CONTROL VALVE -- A premium original equipment replacement part that is responsible for the regulation of idle speed; Ensures that the right amount of air flows around the throttle to achieve optimum fuel efficiency and engine performance; With Standard's limited 90-day or 3,000-mile warranty.

So I'll be checking this control valve along w/the TPS...& doing a cleaning of the throttle body...

The condition described on the Lincoln is call Vapor Lock. This occurs when the vehicle is at normal operation temperature after driving and the vehicle is turned off. When this happens the fuel injection system loses pressure and creates what is called a vapor lock. The fuel injection system operates from 30n to 5o psi. When the engine is cut off the system is suppose to maintain residual pressure keeping the fuel from boiling in the system causing the vapor lock. The electrical pump is located in the fuel tank on this car and will not create pressure when there is excesslve vapor in the system. There are three things that can cause this problem. First a leaking injector, secondly, leaking fuel pressure regulator, and finally a faulty fuel pump. You need special equiptment to inspect the fuel pressure performance. Normally this type of conditon occurs doing warm weather. A long road trip will create and excessive heat load on the Electronic Fuel Injection system and caust this condition occur. I hope this information helps you understand how the system works.
