I would suggest replacing the fuel filter and at least checking the spark plugs condition.

2003 Lincoln Navigator, started bogging down on me and jerking when I tried to pass a vehicle that was doing 55 in a 65mph zone, I let up off the gas a little n it ran fine, but driving back home goin


Check it for codes

You most likely have a couple bad COP Ignition Coils,
possibly a bad EGR Valve or TPS Sensor

All those are common ford & lincoln items

Change the oxygen sensors just before the exhaust converters
if you have 100,000 miles on it

Replace the Gas & Air Filter & clean MAF Sensor with CRC MAF
Cleaner

Install New Spark Plugs

All I suggested should have beeb done when you got it

All your vehicles as well---It is called Preventative Maintenance

Generally, fuel problems cause an engine to lack power.
If the check engine light is on you should have it scanned for trouble codes. The fuel filter should be replaced every 30-50,000 miles and the air filter checked at every oil change.

My car is sluggish till 2nd gear/ just had an oil change and spark plugs replaced, throttle cleaned...shop said that l could also need my timing belt changed has 219,000.00 kms..it is running more rough...


Have the catalytic converter checked out. It may be worn out inside and causing an exhaust restriction and thus loss of power.

None of what you had done,had any bearing on the problem your having.

You need a clean fuel filter and with that mileage,replace the O2 Sensors every 100,000 miles or less.

My jeep wrangler just passed 100,000 miles, what service does it need?


Here is the basic maintenance list for your Jeep:

~ Inspect lights and check tire pressure at least monthly or before & after each trail ride

~ Oil & filter change, chassis lubrication, differential and transfer-case fluids every 3,000 to 5,000 miles or 3 to 4 months - if you have recently crossed through water deep enough to submerge the centre of your hubs, replace the differential fluids as a precaution

~ Underhood belt and hose inspection every 3,000 to 5,000 miles or 3 to 4 months (every oil change)

~ Tire rotation and wheel balancing every 6,000 miles or every other oil change - driving offroad can knock wheel weights off a wheel, so you may need to have this done more frequently

~ Brake inspection every 6,000 miles or every other oil change - if you have rum brakes in the rear, ensure they are cleaned after each trail ride where you encountered deep mud/snow

~ Replace air filter every 12,000 to 24,000 miles or as indicated by inspection - dusty trails can shorten these intervals dramatically

~ Replace fuel filter every 24,000 to 100,000 miles

~ Automatic transmission service every 24,000 to 100,000 miles

~ Wheel alignment check every 12,000 to 24,000 miles or as indicated by tire wear - offroad driving can knock wheels out of alignment, so budget for an alignment every 3 months, then watch tread wear to see if it's needed

~ Cooling system flush and refill every 40,000 to 100,000 miles

~ Belt and hose replacement every 60,000 to 100,000 miles or 5 to 8 years

~ Engine timing belt replacement every 60,000 to 100,000 miles (when equipped) or 5 to 8 years

~ Air conditioning performance check annually, usually in the spring - be sure to run your A/C during the winter for brief period to ensure all hoses and valves stay lubricated and operable

Timing chain needs to be replaced every 100,000 miles? And what the major parts needing to be replaced for the 100,000 mile mark?


You will have a timing belt on your vehicle that is usually replaced along with the water pump. At 100K miles i would do the following: 1. Timing Belt and Water pump replacement and Serpentine Drive Belt replacement. I suggest replacing all the cooling system hoses, replace the thermostat & radiator cap and flush the radiator since the cooing system will be drained and fill with new coolant/water mixture. 2. Check the motor mounts and replace if necessary. 3. Replace the spark plugs and wires. 3. Check the cv joints for broken or cracked boots and replace if necessary. 4.Have the transmission/transaxle serviced and filled with new transmission fluid. (This should be done every 30k miles) 5. I also suggest oil and filter replacement, air filter replacement, have the brakes checked and the tires rotated. It is a good idea to have the thottle body cleaned and the fuel filter replaced also. All of these should be done if they have not been done already. I believe in preventative maintenance and if you can catch problems before they get too serious you can save yourself a lot of time and money. I hope this helps. Please rate me on my answer.

Ck your exhaust pipe at rear of car noting any obnoxious smell like rottrn eggs. Hold a piece of paper, I use a dollar bill ,in in front of the exhaust. If it blows the paper gently, you have a catalyctic converter going or is bad. Will need replace if so.
