Question about 1997 Mercury Mountaineer
I have a list of problem with my mercury mountaineer: for one it Idles pretty bad when it's not in drive and it hesitates when switching gears. I already had a tune up a couple of month ago, but it started doing it again. Two I can smell gas coming from somewhere in the engine compartment. Three the wires inside of the car seem to get really hot whenever I drive for a long time. Can anyone tell me hw can I fix all of these problems?
This car you are driving is 20 years old. Have you thought of getting a newer model? It sounds like you are having too many problems.

I'd be looking at the idle air control valve on side of throttle body. It regulates idle under load conditions such as when turning, AC on, heater etc, brakes applied etc, & steps idle up to maintain proper idle.When this goes faulty it lots of times doesn't send a code. You may get away with just pulling it off and cleaning plunger & port it comes out of with throttle body spray cleaner,It's worth a try before you replace.

it means the catalyst is worn out, the efficiency is monitored by sensors, when the Cat falls below a certain reading or "threshold" the code is generating telling u that u need a new catalytic converter.

Yes it can be related. If you bought the car from a car lot you may have a window sticker showing a 30 to 90 day warranty. The Catalytic converter can be expensive although it is similar to installing a muffler or header extensions.
The hesitation can be due to the engine controls trying to adjust for the difference in exhaust readings from one side to the other. Or it has excessive backpressure caused by the plugged catalytic converter.
