Lincoln 2003 Acceleration

I have a problem when accelerating at 80-100km (around 65mph), the problem is that the car seems to lose power for fractions of a second so I can feel a slight shake/stutter/hesitation. I think it might be something with not enough fuel entering the engine or there might be air in it? The problem stops at higher speeds above 100km so it's only at the specific 20-30km range that this occurs. Other then that there is nothing wrong with it, only happens when accelerating harder or going up a hill.

If anyone has any ideas please post.

Has the fuel filter been replaced? Also clean the MAF with MAF cleaner. If you have an Autozone nearby, they'll scan for codes for free.

It may also be possible that you have one or more bad COPs (coil-on-plug). They can be tested with a multimeter.

Re: Lincoln 2003 Acceleration

yeah KStromberg is right the thing about navi's is that the coils are very scenceitive to water, or there just old i have a 98 navigator and it has about 198,000 mi on it and about a year ago it did that, when we put the computer on it the code reader said "cylinder __ MISFIRE" (but in oder to get a code the cheek engine light needs to be on) so scnince then one by one they all got replaced when it did that. and everything was fine after that

Re: Lincoln 2003 Acceleration

100K miles? It might be due for tune up #2! More so new plugs. If the truck went in for a 60K service, chances are good that the dealership used copper core plugs, which are good, as they're my choice, but they should be replaced every 30-40K depending on how you drive.

Also, with 100K, you might want to consider a transmission service as well (not a flush), and a 4x4 service as old dirty oil can add drag. If you drive in overdrive at 80-100km/h the engine isn't turning over much either, say 1500-1700rpm depending on your speed and axle gearing, so if you have a decent load on board, the transmission will lug some until it decides to downshift or you put the go pedal down a bit.

Another thing to try first, is to put the transmission in 3rd gear, and drive it at the same speeds on a local rural road for five minutes or so. Engine speed will be in the 2500rpm range (or so) and that will rule out any engine lug, and if the engine gets very raspy or sounds different than normal, then I advise a tuneup..
