Question about 1999 Ford F150 Regular Cab

1 Answer

Changing plugs or flushing the infectors?

I have a 1999 Ford E-150 with 88K miles. I haven't changed the plugs in years. Running good, but thought it would be time to change or just do an injection flush of some kind. Any thoughts on it?

Your money is better spent getting some lucas injector cleaner instead of the flush LARGE BOTTLE for about 10 bucks, add 3 ounces for every 10 gallons and this doeas a real good job of cleaning injectors and also lubricating them and the top end. I have a 4.0L ranger w/88K and they are clean, I removed one just to see how it looked and it looked new, no deposits at all.. I put some in monthly and all my cars are performing better MPG wise.. one of them is a 1990 BMW 210K miles and they look almost new. I started using it on the BMW and after the great results there I put it in all my cars like Mom's Castor oil.... Keeps 'em regular.. :o)

Change the plugs... They say they are good to 100K Ok maybe but your fuel mileage will suffer as will your performance..

2011 Ford Fusion, 49000 miles, Oil changer said my transmission fluid looks old and i should flush my transmission and refill it for 125$ thoughts?


dos'nt cost that much find good car repair shop and yes you should put in new filter and replace what fluid was lost during process. i never change all my trans fluid but changing filter makes big improvement. Should cost around 75 dollars from good repair shop or do it yourself for less.

1999 ford contour hesitates when accelerating?


I would check all of the vacuum lines to check for any damaged or cracked ones. If none, when was the last time you did a full tune up on this car? Plugs, wires, air filter(s), oil change, radiator flush, transmission fluid flush! Without first knowing how many miles are on this car, and the last time any of this was changed, it would be a hard diagnosis.

When my 2002 grand marquis hits about 40-45 it starts to ****. I thought it might be water in the gas but I have put in seafoam and dry gas with no change. You don't feel it when you are accelerating...


Waste of money to add ANYTHING TO FUEL TANK
Non of those products are necessary or do much

The spark plugs get changed every 3 years or a little
more & not more than 60,000 to 70,000 miles on them

You could have ignition misfires, very common on all
ford products (not from the spark plugs)

I would be disconnecting any vacuum hoses to the
EGR Valve,plug them & see if the problem goes away
If so,replace egr valve. (another ford problem)

The front 2 -- O2 Sensors (ones closest to engine,before
or in the inlet of exhaust converter,get replaced every 100,000
miles. (not all 4-just front two)

Clean MAF Sensor --- in inlet air ducting (between air filter &
throttle body (CRC MAF Cleaner)

While changing Trans Fluid ---fixes nothing --- it should be done on
ALL Vehicles, every 3 years & NEVER over 30,000 miles
Change NOT FLUSH

Do Power Steering at same time (do flush)

What does a major tune up for a 2004 chevy impala consist of? What should be done and needs to be done?


New spark plugs, oil and oil filter, transmission flush and fill, fuel filter, air filter, coolant flush and fill, clean throttle body plate and bore, clean the MAF sensor, replace any loose or cracked vacuum lines, PCV valve, new air filter, new battery.

99% of the time all you should ever need for a tune up is new spark plugs, and a clean air filter and throttle body. But since your inquiry indicated "major" I gave it more critical thought.

I have a 06 ford fusion 80,000 miles. recently I have had a jerking problem from the rear. The first time this happened I thought someone hit me from behind.


I am only going to guess

You may have a bad EGR Valve,if it slams,bucks,etc,with the slightest amount of gas applied or won't go up any hill. Disconnect the vacuum lines to the valve,plug them and road test to confirm

I hope you have changed your trans fluid, at least twice in 80,000 miles (I used to own a trans shop)
Forget the TV Ads and owners manual,change it and flush the power steering,every three years,not more than 30,000 miles
Flush brake fluid ever two years.

If you still have problems, consider the Trans Solenoid Contol Pack,( remove trans pan to replace)
If the tach ever flairs up, and the shifts are not crisp,stop driving it immediately and change solenoids

When do spark plugs need changing


Ford recommends 100,000 miles on the original plugs. That is ok to do as long as it isn't missing or giving you any indication that they need changing. I hope this helps.

Should a 2005 Taurus with 100,000 miles have the water pump replaced as preventative maintenance? What about the timing chain/belt?


Yes it needs to be replaced its already time for that.
IntervalsHere is what I recommend for maintenance intervals. There are exceptions to all of these including severe duty, which most northern cars fall into.

  • Change Transmission filter-30,000 miles, 90,000 and 150,000 miles and fluid at 60,000, 120,000 and 180,000 miles.
  • Change oil every 3,000 miles or 3 months, unless you use Mobil One, in which case 6 months/6,000 miles.
  • Chassis lube every 3,000 miles, assuming there are fittings.
  • Spark plugs: Conventional plugs: 30,000 miles, Double platinum: every 50,000 miles (100,000 mile plugs are best to be changed well before that, although some can reach it).
  • Fuel filter: 35,000-40,000 miles. Unless it is in the tank. But if the tank is ever dropped, do it then
  • Ignition cap, rotor, wires: 60,000-80,000 miles. (if it has them).
  • Timing Belt, if applicible: 60,000 miles on many but check with gates or dayco or the manual or dealer, as many different intervals are now present.
  • Coolant flush -- green: 2 years/24,000 miles.
  • Coolant flush -- dex-cool or long life: 5 years/50,000 miles.
  • Tire rotation: 5,000-8,000 miles.
  • Alignment: 15,000-20,000 miles., unless tire wear is not a problem and car goes straight.
  • Brake fluid flush and power steering fluid flush: 2 years or when dirty or discolored.
  • Air filter, pcv valve and cabin air filter: as needed.
  • Professional fuel injection service: 40,000 miles.
  • Throttle bore plate cleaning: 20,000 miles.
  • Air induction service: 20,000 miles.
MaintenanceEvery auto manufacturer lists their required maintenance on their web sites and in the owners manual the maintenance service intervals vary between manufacturers.

Your car is a moving piece of machinery, it needs maintenance, if you want this car to last you need to service it. Do not just do the minimum recommended services that are listed in you service manual. Make sure you service your cooling system which prolongs the life of the radiator and water pump, and the power steering system, which will extend the life of your cars power-seeking pump and gear box or rack. It will cost you much more than you want to spend when you fail to maintain your car and larger problems surface. I recommend that you review your owners manual and get acquainted with a reputable auto repair facility. A good relationship with you car and your car's mechanic will benefit you in the long run, providing you with a long lasting and safe car.

At 30,000 miles you should also service your cooling system, transmission, fuel system and power steering; this should be repeated every 30k miles. I recommend flushes of the later mentioned items to prolong these systems' life span.
