It is an old trick when plagued by a persistant light to disconnect it, especially if it is a used vechicle just purchased.

    Hi. You would have to take it to a shop to have a qualified technitian check to ensure how the light was disconnected or turned out.



    When doing that, it is also very necessary to tell the shop what and why. Sometimes they will be helpful, because of the dislike for dealerships, and sometimes not, because they don't want to get involved.



    what you are dealing with is the used car department at the dealer. I know, because I ran these departsment for a number of years. See, I am telling on myself. Many times their tactics are less than desireable.

2000 ford f150 has exhaust leak bought from dealer in may and code p0320 comes up and smells of burnt oil how dose this get fixed, is it expensive?


Here's the Ford discussion on it:
P0320 2000 Ford F150 Ignition Distributor Engine Speed Input Circuit...
It's not an exhaust issue. P0320 means that one of the ignition coils did not get an electrical pulse to make a spark plug spark.

On certain Ford models, one of the underhood wires rubs against an air conditioner tube and chafes through the insulation causing this fault. You can separate the wire and wrap it with electrical tape and use a cable tie to prevent rubbing. Here's a YouTube video which shows an easy way to fix it.

Tried getting ford f150 4.2 2003 inspected. Replaced air filter and fuel filter already. Check engine lit was on before replacing them . Now check engine light is out . But won't pass inspection.


As for your codes p1131 and 1151: Ford - Lack Of Heated Oxygen Sensor Bank 1 Sensor 1 Switches - Sensor Indicates Lean


Last week I had the very same catalyst, evap and ECG codes come up on my 1999 Mercury Mystique which is like a Ford Taurus. A friend was able to find a hole or leak in the hose connected, replaced it and it runs fine. I havent run it a full and straight 50 miles yet to clear the check engine light but that repair alone changed the entire way the car was poorly driving. Im sure that hasnt fixed all the probs but thats a good starting point.

My husband was changing the front brakes on the 2003 F150 and broke the brake line. Will it be difficult to fix?


NO. The line will have to be replaced & the system bled to remove air. Parts are readily available locally at your parts stores like Autozone & PepBoys.

It is best to use 2 people to bleed the brakes after the repair so you both may need to be on talking terms.

good luck

2003 F150 engine chugging when i accelerate


Check your fuel pump or even your air intake could or might be loose or your putting cheap gas in your vehicle.
If your truck has a V8 I would suggest using 91 octane at Chevron or a Texaco.
