Question about 2002 Ford Windstar Cargo

1 Answer

Why would I get a big chunk of carbon buildup on the sparkplugs with only 7000 miles on them and only on 3 of 6 of them. It's whitish beige in color and a quarter inch of buildup.

    Have you had a compression check done? The deposits on spark plugs are shown on a plug chart at the auto parts store. How many miles are on the engine? High miles could have caused wear on the valve guides. Does the engine smoke or use oil? Has the oil been changed frequently? A good service center could help you diagnose the reasons for the build up. I'm sorry that I can't be of more help online.

That would be indication of weak spark (plug wires) you can test them if you have an ohm meter - anything over 8k ohms per foot - toss them. I would start there.

Carbon built up on sparkplugs on one side and truck seems to consume extra gas


That carbon buildup could also be unburned fuel - - depending on the make model and year it could be injector problems.

Misfire on 3 and 4. 2001 4.6L F-150


There were a number of problems with V=8 engines in this Series. Some of the sparkplugs would try to leave the engine on their own. You need more testing to know what is wrong.

I will try to explain. The trouble Codes generated by your Onboard computer can be too general to identify a specific part for some problems.

There are 3 causes for a misfire. Fuel, spark, and compression. You can have fuel injectors which are dirty or have bad connections or coils and fail to open consistently. Spark issues are more complicated to diagnose as coils are now attached to individual sparkplugs(some models) and are triggered by Crankshaft and Camshaft sensors. A bad coil-pack feeding each bank of sparkplugs can short out adjacent plugs like #3 and #4.

Compression problems between #3 and #4 cylinders from a bad head gasket can cause misfires.

You can get a loaner test kit for the fuel injectors or use a test light or multi-tester. This will eliminate or confirm the fuel injector circuit as the problem.

There are cylinder balance tests that are non invasive when done with a good scanner. Otherwise removing the sparkplugs will be required to do a compression test.

Sparkplugs leaving the engine: They either unscrew or rip out the sparkplug hole. Loose plugs will misfire. BUT there is a problem with removing sparkplugs on these Series of motors. The factory plugs are 2 pieces welded together. Carbon buildup causes the sparkplugs to come apart as they are removed. Use solvent every 1/4 turn, let set for first 2 twists.

There was a Recall on these motors, but a Mileage limit and a time limit of about 7 Years was imposed. Check Internet for articles about all of these subjects, photos, etc.

Please rate my info.

I have a 2005 town car just had to replace converter it had a rattle now i have a p0401 code


Check the passages and pipes,etc on the EGR valve for carbon buildup.The valve itself could also be plugged up,or a large chunk of carbon has broken loose and is restricting the flow.I remember the guy in the stall next to mine bringing a friends Town Car in with the same issue,and we cleaned the pipe out by stripping a 4 guage alternator wire's insulation,and chucked it into a drill,fed it into the pipe,and used it to brush out the carbon.It took a while,but it worked!

Starting to see white smoke coming from my tail pipe, what could it be?


**** smoke is water vapor, could be a sign of coolant gettting into the combustion chamber, best to get it checked ahve the coolant pressure checked, and remove the sparkplugs, they should be dark colored if any are a whitish color i would suspect a head gasket

How many miles between oil changes.


You should change your oil every 3000 miles. I have heard some people say 5000-7000, but trust me every 3000. I can't tell you how many times I rebuild an engine where the owner didn't change it every 3000, and the about of buildup is terrible. Hope this helps.

Hi! Try replacing your sparkplugs. It may be full of carbon and causing a reduction in fuel economy. New sparkplugs can perform better fuel burning. Hope this helps

Ignition Distributor location


There is no cap and rotor, as the vehicles igntion system is DIS (digital ignition system). The recommended tune-up on these motors require sparkplug and coil replacement. The coil type in this vehicle is COPs (coil over plugs). Usually moist and oxidation develope on the sparkplug chamber walls from faulty or worn coil boots. This causes the coil to short, they must be replaced at 75,000 miles at the same time the sparkplugs are replaced. Typical symtoms are: Vehicle stalls (restarts and runs normal), intermitted jerks/sputter while driving, misfires, rough idle, severe power loss. Hopefully this helps

My 2000 ford excursion 5.4 v8 gas has a problem at idle every time i come to a stop the idle remains at 1300 rpm for about 2mins then slowly returns to 7000 rpm also has slight miss on accell


Ethanol gas syndrome/ buy a can of SEAFOAM(parts store). change out the fuel filter. add SEAFOAM to full tank of PREMIUM gas. let it idle(even if you have to make it by acceleration in park)/ drive 10 miles, replace fuel filter again at 500 miles. add can of SEAFOAM every 3-5000 miles, and it will clean fuel,emission, and engine valves.<p>
ethanol produces a goop(like choc milk) and creates water in the system/ It causes carbon build up and even affects injectors. If you will try this, it will help prevent costly repairs/ cost 8-9 dollars for the SF. whole lot cheaper than an engine job. good luck.
