    #2: If you have a condition that a technician can't easily duplicate, they are not going to spend a lot of time trying to find it. That's not how a tech gets paid. He might get paid 45 minutes of time to diagnose the problem (probably more like 30). So he drives the car and it's normal. He pulls the codes...but there aren't any. Well...45 minutes have passed and he isn't getting paid anymore. So you put "unable to verify customer concern" on the work order and you get on to the next job so you can keep getting paid.

    It would be easier to get a first/second opinion if the condition could be easily duplicated first.
    #1: You don't need a Mitsubishi Scan tool for these cars. I would except most decent shops to have a decent scanner by now. If a shop only has generic OBDII code reader or an amazon bluetooth special I'd find another shop ASAP> EDIT: I know the tpms is screwy mitsu only crap but everything else should be able to be read by a relatively cheapo Autel Scanner, I haven't used a snap off one in years so Don't know how their updates or compatibility work. Maybe you have to purchase mitsu only software at stupid prices?

    #2: I can't wait to get home and have a beer!

    I've had the same thing happen a few times lately. Like a stumble. The first time, I was on a hill, released the brake, pressed the gas pedal and nothing! A second later, the car took off.
    A few weeks later, at a stop, it idled rough like it was about to stall. I pressed the gas slightly and it smoothed out.
    Then tonight, on a steep hill, the car missed, just like it slipped or something.
    2015 cvt with 91k miles.

    If this crap keeps up, I'm going back to a carburetor

    If your going up a real steep hill the "B" or low gear, is a life saver reducing the wear on your CVT I believe. Im glad to hear these issues on this thread could be something entirely different than having to buy a brand new $5k CVT.

    If it were mine, I would do the following:

    1) Check the function of the pedal by OBD. See that the gas demand caused by pushing the pedal actually results in a gas demand to be seen by OBD. Since these pedals have optical sensoring and very seldom have any problems at all, probably it is something else. If you have no OBD gadget, proceed as below.

    2) Check other electrical stuff, like:
    Is the pedal sensor connected properly?
    Does the handbrake warning light function orderly and does it go on and off when you pull and release the lever?

    3) Most important: Check the entire connectors to the left of the drivers left foot for minute signs of corrosion. (See other threads!) These connectors can corrode easily if they get moist, and that will cause havoc. The corrosion is often hardly visible, and frequently occurs between the actual crimped wire and the pin of the connector. You need a very good look and a strong magnifying glass to really check the condition properly.

    Be sure to take your time to have a very thorough look, or you will not see problem-causing corrosion even if you are holding the culprit in your fingers!

    These measures cost nill Dollars and you can do them all yourself!

    OP needs to get a professional assessment and then get back to us. This forum has saved me alot of money this past year thanks to Fummins, Top Fuel, Mark, etc. but I always follow up the quality advice I receive on here with an actual physical diagnosis from my private mechanic. 9 times out of 10, they usually match up.

    So nitpicky. I like it.

    Hey Cwick, time to make a forum Garage entry and start keeping track of all the changes made to your Mirage.

When you unplug the seat airbag there is a little wire that shorts the circuit going to the bag literally making it impossible for it to go off. Unless of course you cut the wires closer to the airbag itself then supply power and ground to them. I wouldn't run around in wool socks on shag carpet touching the connector on a wheel airbag that doesn't have a wires hanging off it but the likelihood of one going off accidently are slim. I've only had 2 go off accidently, one was while trying to pull out a front end loader with an f150 and a chain hooked to the hitch. That didn't go well. Both front air bags went off when the chain got tight. The other time was when I was setting them off for fun, had a bunch of old crown vic bags laying around. Cut a pigtail from one car and hooked it to a long length of speaker wire, hooked it to a booster pack and boom. I forgot to unhook the booster pack before plugging in a fresh airbag and it went off in my hand. That stung for a minute.

    Got a little sidetracked. The connector I was talking about is under the carpet, you gotta pull the seat to get to it.
    That's why airbag squib wiring connectors get shorting bars - because they are susceptible to static electricity. Few other electrical circuits get this treatment.

    Junkyard science experiments pay off. The More You Know!

    Reminds me of Dances With Bulls. John Dunbar's Shorting Bars.
