Not sure about checking the code unless you go to a mechanic and pay them to check it for you.  As far as what is wrong, it sounds like your idle air control valve is bad.  As its name says, it controls the idle for you vehicle.  The IAC is located on the throttle body and is held in with a couple of screws.  Change this out and I bet your problems go away.  Let me know if you have any questions.  Thanks for rating my response and for using FixYa!

Try this. disconnect battery.30sec reconnect. Hold engine at idle until it idles by itself. leave idling 20min.Computer can "forget" how to idle engine if battery has been replaced or disconnected.Dunno about check engine light.May disappear after bat/dis. Otherwise check wiringconnections around engine.

I have a 1991 Mitsubuishi mighty max truck . The truck runs fine until I drive for about 1 mile and then the check engine light comes on and the truck starts shaking , but does not lose power.


Hi, I own an 86 Mighty Max truck myself. Is there anyway you can get the code number for the engine light coming on. It could be many things that cause this problem. Fuel filter, EGR, Clogged Catalyst, Sparkplug Misfire, Cracked Distributor Cap, the list goes on. It needs to be determined if the problem is fuel or electrical related to help diagnose the problem.

1994 Mitsubishi Mighty Max, 2.4 injected. Truck would start but idle way up then down almost stalling. After warmed up it would idle decent and drive, but under load it had no "pull" and...


Hello brian..these are great little trucks, i have a 87 (hitachi carb) with over 300k on it---still going strong and gets good mileage. Sounds like a fuel delivery problem on yours--- You can test the fuel pressure and the pressure regulator with a manual gauge...autozone has loaner tools if you dont have a fuel pressure tester. You should have aprox 36 psi ---remove the vacuum line on the pressure regulator with the engine running, the pressure should come up about 5-10psi, if it dont the regulator is bad. (Make sure there is vacuum on that hose) Make sure the MAF sensor is clean, if dirty clean it with MAF sensor cleaner, don't use brake cleaner.

Check for vacuum leaks around the manifold and emissions hoses...a good way to do this is with carb cleaner...spray it on the areas you are checking, it engine rpm change, you found the leak.
Also check the coolant temperature sensor, if it is out of range it will send a false signal to the engine controller, the controller will not open the injector circuit to squirt enough fuel under a load.

I hope this helps & good luck with your mighty max.

How do I read the check engine codes on a 1993 mitsubishi mighty max?


At the ECU there is a connector that you use standard analog volt meter. In using the twio proper PIN connections the ECU will give yoy a type of Morse code to determine engine and sensor errors
If you like I can email you these codes.
Best regards,
Tom

Engine backfire's when you let off gas but idle's fine


Engines backfire when timing has slipped. You might need a new timing belt. \

Timing belt goes from Crankshaft on bottom of engine to Camshaft on top of engine. Both have to be synchronized to the correct timing.

Check repair manual or internet for correct timing. You'll probably have to find top dead center on first piston.
