How to reset a computer on a mercury cougar 2001

Use a OBD2 fault code reader or scanner to reset the system. A full wipe is done by disconnecting the battery negative cable for 5 min's. I do not recommend this as you will then loose all stored and learned engine and transmission data and have to perform an OBD2 drive cycle test to complete/pass any emission testing required.

How to disable "Service Engine Light" on 2004 BMW 325i

You can't. You have to read the engine fault code with an OBD2 reader, fix the fault and then reset it. They are not really "you should get this car serviced" indicators, they are an indication of a serious fault as detected by the engine management system.

Have 2001 mercury sable LS changed plugs, wires, egr valve after the computer said it was egr valve. still have a bucking problem. what could it be?

Computers do not diagnose your vehicle
They do not tell you what is wrong or what
to replace.

Study OBD2 Systems

You just got an EGR Code,that
had to be diagnosed

Need to check codes on my 2000 mercury sable, I don't have a diagnostic tool. How can I check code? can I jump pins to get flashing light codes?

No, you can't.obd2 requires a code reader to read the codes and you can't use the check engine light anymore.It is usually cheaper to buy one at walmart then to get someone to hook theirs up,check your options,you might want to buy one.

Car shuttering an and check engine light flashes

Get a hold af a code reader ( OBD2 ), and read the codes. The car is telling you something. Let me know what it says, and I can help you better. You can borrow one from some auto parts stores, like AutoZone, or get a cheap one for $35.
