The steering wheel is very stiff and I thought it would need power steering fluid, but it was full. What else could be wrong with it. I heard it could be the band or belt. But I cant tell. And I just baught this car not even a month ago. And the windshield wipers turn on everytime I turn right. :(

Have you bench test the coolant temperature sensor-could also be the idle control speed device and coked up throttle body that needs cleaning.

The rough idle starts reminded me of a engine that had just had a timing belt changed before the timing had been adjusted. The dealer had also mentioned an EGR valve had intermitent problems according to their diagnostic machine. I was reading a Chilton's manual and saw that a throttle position sensor could affect timing. I replaced this sensor and cleaned the mass air flow sensor along with a similar air sensor mounted next to it and that solved the problem. Since I did these three things at one time, I am not sure what solved the problem.

The dealer wanted to charge me over $1,900.00. The plug wires they wanted to replace where actually the individual coils found on the 5.4. Its hard to believe that dealer's mechanics rely so heavily on the computer diagnostic equipment even though the diagnosis does not make sense with regard to the symptoms I described. The dealer was going to change the EGR, starter, 3 coils, 3 plugs and do a radiator flush. They told me the starter was bad because I had mentioned that at one time, the rough start sounded like a starter that was not engaging the flywheel or a starter turning an engine over with no compression.

"could also be the idle control speed device and coked up throttle body that needs cleaning." Your answer was right on point. Thanks
