I am a single female in school with no family so appreciate anyone who may be able to help me on this issue. The car only has 76,000 miles on it (it only had 12,000 when I bought it in 2005) and I totally take care of it with regular maintenance and service as I have to be able to rely on it. I was leaving school and went to turn on the fan to high inside the car and put on the air conditioning. Nothing worked-the fan would not blow any air out and the air conditioning would not go on and the light for the air conditioning would not light up. I immediately pulled over and parked and sat for 15-20 minutes or so. Started the car and the fan and air conditioning came on with no problem and everything seemed fine. Now the car is idling really rough, tries to stall at every stoplight; I have to put it in neutral and keep foot on gas so it would not stall on me. Took it to Auto Zone and they hooked it up the computer to see what the codes were and this is what it said: "Random cylinder miss fire P0300" Probable Cause: 1) Ignition system faulty 2) Fuel system faulty-injectors or pressure 3) vacuum leak 4) engine mechanical condition. Auto Zone said to start with the first issue and said I should get new spark plugs and wires as I had not done that yet since I bought the car. I had a friend of mine install new spark plugs and wires and I can hardly get it to go over 40 miles an hour now and it is even worse than ever. Took it back to Auto Zone and received more codes: "P0130 Heated oxygen sensor 1 circuit fault" and "P0102 Air flow circuit low input." I am on my 3rd radiator, have a brand new compressor for the air conditioning, treat the fuel system every 3,000 miles when I get an oil change and I use a synthetic blend for my oil. Does anyone have any ideas for me? I appreciate any help or ideas you may provide.
You need to find a mechanic that will actually scan your computer to see what each component of your engine and rest of your vehicle is doing, not just pull codes. There are sooo many things that could cause your issues...

with the battery fully charged try scraping the positive over the terminal on the battery and see if it sparks like a draw is sucking out amps if theres no draw on the battery it wont spark at all (good) if it sparks (bad) you have something grounded and killing your battery.. gl

you have to see if the coil pack fire up do you have spark coming out of the coil pack cylinder 2 never mind the other code the missing cylinder make the other sensor malfonction check if you have spark coming out of the coil pack if not change the coil pack if you have you spark check the compression let me know pierre please dont rate right away we work together to fix our problem because i whant you to get our car running good and i whant a fixya anything else is bad for me thanks pierre
SOURCE: '92 Mitsubishi Diamante - Stalls sometimes when come to a stop
find the Idle air control valve on the side of the intake and then take off and clean or replace you could try taking a small ball peen hammer and tapping it lightly while it is idling let will genarly free them up
SOURCE: lack of power, hesitation, #1 miss firing
you may need to perform a leak down test to the cyliner and maybe you may have carbon on that valve. make sure the new spark plug wire has the correct continiuty
SOURCE: 2002 Mitsubishi Galant ''hissing noise''
I would first try to locate the source of the hissing. Try spraying some engine starting fluid around the hissing area and home in on the source. The engine revs will change as the starting fluid is drawn into the engine. Sounds though more like a vacuum as you have suggested.
