check engine light

have a 91 lincoln town car with an intermitant check engine light that just started flashing. Is there any way to self diagnose the problem?

Dude, run to your nearest Auto Zone with a service bay, of course. Have them run a FREE engine diagnostic test and tell you some codes. THen you cut and paste Joe's link for Autolibrary.org I believe, input the year and model of your vehicle and they'll interpret what the codes mean. Ba Da Bing!

The links and posts in my signature file already have that information Sean .

If not, you are 100% correct, Autozone can run the needed scan to pull out the trouble codes.

AutoZone

AutoZone do not have service bays either. They come right out into the parking lot to help you out.

My only complaint w/ Autozone is that they read the codes & then attempt to sell you a part that you very well may not need.

For example, many mid-'90s & up Fords suffer from dirty Mass Airflow Sensors. When the MAF gets dirty, it sets Oxygen Sensor codes. The codes point to the O2 sensors, so the counterperson tries to sell you a couple of O2 sensors, when in reality you need $4 worth of cleaning solvent to cure the problem.

The trick is to have them read the codes and then ask us .

Lol. Besides that, O2 sensors should be changed regularly. They are not failure type items.

Now I am upset.........

I thought what a great job I had done, replacing the MAF, at $67, and now Knuckles is telling me that I could have cleaned it for $4. Tell me that I did the right thing, please. Lie to me if you have to. LOL

Clean it?

Now Sean, why would I clean it if it is new? Is there another part to it?

I think I might leave well enough alone. LOL

Cleaning works sometimes, replacement is needed in other cases.

You can ruin them if you are not careful about cleaning them.

There you go
