Question about 2002 Mitsubishi Galant

Tune-up; low RPM at idle

My 2002 Mitsubishi Galant, 2.4L 4 cylinder engine, has begun idling very rough, though there are no trouble lights on.

    All the plugs and both ignition coils were changed within the last 12 months. Could it be the timing screws? Or a bad 'chip?' I thought the Galant 'tunes' itself?

Do i need a compute to the rpm up in a 2002 mitsubishi galant


the computer is preset for rpm at idle it sets the timing -fuel ratio-etc to raise the rpm for what ever reason you would need to reprogram the computer --the transmission-and all sensors are effected also ---none of the programs including racing mess with the idle so you would have to make your own engine management program to raise your idle

Rough idle on 2002 Dodge Neon


Without trouble codes you are fishing in the dark. If the engine has a cylinder that is dead at idle from a fuel injector or ignition problem, it should have a code for a miss on that cylinder. A mechanical problem like a burned valve could cause the problem without setting a code. Have you checked compression on all 4 cylinders ? ?

-----------------

Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.


To confirm the problem, the basic troubleshooting is required.

My 2001 Mitsubishi Galant 4 cylinder is idling high in park and when put in drive it starts idling low, runs rough, and acts like it wants to die at stop lights


This is a typical vacuum leak. Check all the hoses. If none are sucking air then use WD40 and spray around the intake manifold. If the engine runs better or changes how it runs then look at replacing the intake manifold gasket.

Car cuts off when idling at traffic lights when air is being used does not cut off when air is off 2002 Galant


your engine idle not keeping up with the demand when you have the air on.Either have you engine properly tuned up,or turn up the throttle idle to about 750/850 RPM or a little higher if needed.Keep in mind if you have to go through this you need something fixed to make the engine run properly with the A/C on.

Rough idle with check engine light


Usually a rough idle on a Honda is a result of the idle speed being too low. What is your RPM suring idle now. Try to increase it using the screw on the idle air control by only a quarter turn at a time. Hope this helps.

your probably feeling a rough idle of the engine. need a tune up?

in park the engine is not loaded down, just idling at a low rpm=rough
in drive with brake on you have put some load on motor also at low rpm=rough
in drive on the road engine is at higher rpm, = smoother

generally 4 cylinder motors idle a bit rough, especially if one spark plug is not firing right or fouled or one bad spark plug wire. tune up may fix it. if it is not stumbling real bad or stalling then you can live with it.
