I have a 2005 Lincoln LS sport and was told today that I have a misfire on 4 of 8 cylinders. I was going to just replace all 8 coil packs does anyone know of any cheap places to get all eight?

You can get them cheap on EBAY but most are made in China and I'm not sure about the quality. I bought mine from a Ford dealer online and paid around $60 each.

I had been having similar problems with my 2000 LS...I had replaced several coil packs over the last couple of years...this seemed to solve the problem for a while then the car started idling very rough...i figured it was another coil problem...the dealer had the car for several weeks trying to diagnose the problem...with no luck. I finally took it home and drove it as is for almost a year...a loud knock started after a few months. not so loud at first then became worrisome. A mechanic friend of mine listened to it and told me he thought the engine was shot. But, i gave the dealership another go and let them keep it for a while longer...after several more weeks of diagnosing they came to the conclusion that the timing belt tensioner was loose making the knocking sound in the engine and also throwing the car slightly out of time (hence the misfiring)...this turned out to be a $700 fix, but it's running beautifully again. Now if i can figure out why it overheated the other day...(This car is driving me nuts, but i love it and can't let it go)

The cooling system on these cars needs to be bled if it has been drained and refilled. Maybe the dealer drained it when they worked on it and didn't bleed it correctly?

Its easy to change the 3rd cylinder, because its on the passenger side and that side is easy to get to. You will need 7mm wrench and socket 1/4 drive, 10mm socket and wrench, gaskets set complete, spark plug, for cylinder 3. I highly recommend changing all coil packs, my old saying is did it done and gone! Wish you the best

Surely mookie3 has already had that fixed in the 4 years since he posted it......

#90 of 111 Lincoln LS '02 V-8 Steering 'snatches' by lincman1

The steering snatches or feels like there is a notch in the first few degrees of wheel movement. Worse to the LHS. Research indicates it is the steering wheel posn sensor at fault. Where is the posn sensor located? Any tips on how to replace it? Thanks.

My best guess is, since you have no errors showing up, it's not missing any charge at the coils so, likely it's the spark plugs well(s) collecting oil. This is very common, the valve cover gasket set includes 4 round spark plug gaskets which fail in time. As they fail, oil seeps into the spark plug cavity and continues to collect oil until there's just enough to ground out the ignition spark from the coil spring/boot to the spark plug tip.
 
Many folks just replace all the coils then later find out they performed a completely wasted repair. While you are in the valve galley, I recommend you check out the secondary timing chain tensioner as they are prone to early failure and are basically right there in front of you once you spend the time to get the valve covers off. This is on 3.9 V-8's. If you have a V-6, forget the above as they don't usually have this oil seepage and chain issue.

Talk to the service manager, 95% of the labor to get to coils is removing the valve covers. Once you do, the coils are less than 1 minute to R&R.
