Got a 1999 navigator w/ 80K miles on it. Just today, it's stalled out 3 times while at stop signs/stoplights. The service engine soon light came on and there's a whining coming from the engine. All fluids are fine. Any ideas?

There's a few stall posts over in the Lincoln Navigator Owners: Problems & Solutions discussion.
This one for example (but only when the engine is cold?).

Thx. I posted over there. Wonder if it's bad gas?

That's a possibility - try a different brand and report back!

I also have a '99 Navigator and have the same problem. My Navigator will hesitate upon acceleration from a dead stop. However, I have learned the problem occurs when the gas is below 1/4 tank. The prevailing theory from the dealer was that there was some electrical issue that kept the ignition from getting the appropriate amount of amps upon acceleration. That didn't make any sense to me given that it only happens when the gas is below a 1/4 tank.
Not wanting to waste a bunch of money chasing a ghost, I have just elected to live with the problem and keep the tank above 1/4 tank.

Clearly your problem is fuel related - pressure obviously playing a part, and it will only get worse, so you won't live with it this way for too long - the truck will get hard to start next. I'd change out the fuel filter first. If that doesn't help it, put a guage on the fuel line and check pressure with the tank below 1/4. I'm betting it's low, meaning your fuel pump needs replacing, not terribly expensive to do. Do it now, or do it later, or sell the truck now.

I have a 2006 Nav two wheel drive. For the last several thousand miles I have experienced rough ideling, not real bad, just anoying. I have it at the dealer but they say there are no codes and they can't figure out what is causing it. Any suggestions?

I just got a used 04 and noticed the same thing. It is not bad or even noticeable by most people, but in my opinion, it does not idle smooth like my 04 mustang. I had the dealer check it before i bought it and was told no codes came up. They told me that the previous owner may have put 87 octane in it and a couple of tanks of premium from chevron would clear it up. After the 4th fillup, i admit it is less noticeable, but it is still there from time to time.

Folks with rough idle problems - You may want to do a compression check - especially on the left bank. See my post 577 in Navigator Maintenance and Repair.
