    Had the triple step fuel injection cleaning service (at Goodyear just to have done quickly) and MANY other recommended things done. So far so good, truck is riding better. odometer seems to be something w/ instrument cluster rather anywhere else. price for cleaning 115 bucks.
    I think this was something WE could have done if we had time. i'll keep u updated.

Loosing power going uphills

By losing power do you mean its RPM is dropping a lot even when you apply more gas? When you get on the highway and try to speed up does it seem hesitant or sluggish as well? This may be do to bad vacuum lines or a restricted air intake. Check the usual suspects like the air filter, spark plugs, spark plug wires and connectors. Check the power cables to the battery and alternator along with anything else. It may be that when your at an angle, a loose connection is falling back and causing the power loss. Me thinks this is the Spark plug wires, there may be a bad one in the bunch. While the car is running, get under the hood and wiggle the spark plug wires and if you get a bad one you will hear the car doing what it does when you go uphill. You can also check the vacuum lines as well.

My 2006 Lincoln Navigator has a problem when it is in overdrive. If the rpms are low and I step on the gas the car jolts back and forth until the rpms increase. It kind of does the same thing in 4th if I...

Your friend could be right. Normally if you have a cylinder miss or a problem with the transmission you would get a check engine light and a trouble code. Low fuel pressure may not show up like that.
You may want to check fuel pressure at idle and on the road.

Sluggish during ecceleration, loses power

A 16 oz can of SEAFOAM motor treatment into the gas tank.

Purchase SEAFOAM at walmart, NAPA, auto parts stores.

Around $9.00 a can.
Be careful putting this stuff in the tank, don't spill on the car's paint!

I do not work for seafoam, I use this stuff and it works!

I put diag tester on 2001 linc nav it said lean 1

If you getting a lean code you may want to start by changing the fuel filter. I'm not that familiar with the Navigator but, If you look at the coil pack they have them numbered. The right front (passenger side) cylinder is number "1" it's 1 2 3 down right side and 4 5 6 on the drivers side, that's for a V-6. A V-8 is the same except 1 2 3 4 and 5 6 7 8.
