Rough idle, stalls in idle and while driving

Let's start with the code reader port issue. The OBD2 port gets its power from the same circuit as the cigarette lighter. It should be fuse number eleven in the image below. Check it to see if it's blown, which it probably is. If that fixes it, get the code(s) and get back to us with them.

When was the last time that the car had spark plugs and wires? Given the mileage on the car, it may be time for a tuneup. If that is not the problem, then knowing these cars as well as I do, I can tell you that the miss is probably caused by a weak coil. This car has three coils, each providing the sparks to two cylinders. You will have to check the spark strength on each cylinder individually. See this guide: https://www.2carpros.com/articles/how-to-test-an-ignition-system.

If you have a coil that is not sparking, you can interchange that coil with another one and see if the problem follows that coil.

Okay, great.

You probably don't need a new MAF sensor, just clean the one that you have. Get some MAF sensor cleaner from the auto parts store, take the sensor out of the vehicle, and spray all around the sensor with the cleaner. Be sure to spray in the same direction that air flows through the sensor, and be sure to spray the sensor filament. Let it dry for a few hours and reinstall it. Also check the air filter and make sure it's clean. Replace if necessary.

You also probably do not need a new EGR valve. You can just take it out and soak the plunger part with Carburetor cleaner. Also spray some in the tube/pipe that goes to the EGR. Let the valve soak for a while (maybe 10 minutes) and then make sure that the plunger moves freely. Use a small screwdriver to scrape out any carbon buildup. Then let it dry a while and put it back in.

The evap system code isn't causing any rough running conditions, just maybe a little lost fuel economy. We can deal with that later.

Ok let us know what you find.

There really isn't a way to test them with a multimeter or scanner, but if you can get a spark tester, that'll tell you something. You'll have to test each cylinder and see watch them closely to see if (1) a spark is weaker on one or more cylinders or (2) if certain cylinders just aren't getting sparks as often. You can also pull the spark plugs and look at them to judge their condition.

You would think that bad plugs and/or wires would throw a misfire code, but that doesn't always happen.

Here's a guide on spark plugs: https://www.2carpros.com/articles/how-to-change-spark-plugs

Here's a link to the spark tester that I use: https://www.amazon.com/Lisle-20610-Inline-Spark-Tester/dp/B0002STSC6/ref=sr_1_3?ie=UTF8&qid=1501325755&sr=8-3&keywords=spark+tester

The cooling fans aren't going to always run. They'll only run when the engine has warmed up some. One of them will probably only run when the AC is on.

In my experience, usually extraneous wiring on a used car is part of a sound system that a previous owner had. So the stuff under the console may well just be that. There may be more wires sticking out in the trunk or in the door jams under the plastic pieces. Poke around in the trunk and under the hood and you'll probably find what they go to.

As far as the phone/posting issue, I don't have that problem with my phone. Could be a browser issue. I use Firefox on android.

I'll email you shortly with 2carpros in the subject line
