I would address the O2 sensor straight off. If allowed to run with a defective O2 sensor you can ruin the catalytic converter in a short time, and that would be expensive. A note on O2 sensors for these cars. Be careful about buying a "generic" O2 sensor because they are cheap. I have, after owning 3 Mitsubishi's found you want to use a name brand sensor, and make sure the mfg. application chart lists your specific vehicle under that part number. You can have some real issues using a cheap O2 sensor. If you do not already have one, you will definitely need something like this to work on these cars. ...J.D.

I have been using Bosch O2 sensors. It depends on what is available in your area. Whatever. Just make sure the part # is compatible with your car, not generic. ...J.D.

Anytime you see the word "universal" it means they try to make you think it will fit anything. Not true. Get the correct part. I have TWICE had this problem. Once with my 97' 2g RS and again with my current 2001 3g V-6. I finally learned my lesson. Not only is there sometimes a problem with the plug not fitting, but more seriously, I got into running problems with generic O2 sensors. They were not compatible ELECTRONICALLY with the ECU. If you cannot find what you need, I can recommend going to a NAPA auto parts store. They have an excellent parts cross referencing database and a huge parts warehouse. They will get you the right part for your application. Not always the cheapest, but you want it to work correctly. ...J.D.

There is more to sensors than making them fit. I did some engineering of computer based systems for automation. Any sensor has to have a protocol that it is built to, and that protocol has to match the I/O port it is connected to. The range of the device could be, for example, 4-20ma, or 0-5vdc, or a simple on/off [0-1]. It also has to have the right "action". R/A= reverse acting [as the control signal goes up, the output goes down]. Of course D/A has to opposite action. Make sure you put in the right stuff. This gets very hard to troublshoot if you get it wrong. ...J.D.
