My 2001 Mitsubishi galant will start and idle fine but as soon as i put it in drive and hit the gas it bogs out bad. what could cause this? i put fuel injector cleaner in it and replaced the air filter but that didn't help anything. anyone have any ideas what it could be or how to fix it? im afraid im going to have to replace the fuel filter but want to avoid that if possible.
SOURCE: Engine is missing and shaking bad when idleing or driving slow
it's probably one of the coils , I'd buy one and try replacing one of the two there ! , let me know how ya make out !

hey common problem w/the 2000 galant. you may need a mirror to see this, look and or feel where your throttle body mates up to your intake manifold. it has a problem of cracking, when you have an air leak there it will run like **** and usually shut off depending on the severity. this will cause you to get the throttle position malfunction code. if that is the case instead of buying a new or used intake manifold. take the old one off, and you can actually cut it flush and weld about a 2 inch in length tube to repair the crack. well let me know how it goes.

If you have spark, try changing the fuel filter. If you don't have spark, get back to me.
SOURCE: Fuel Injector prob?
check your EGR valve a plugged up or not working will make it seem like its the injectors.

I am having the same issue on Mitsubishi Galant 02. Clattering on acceleration, herky jerky idle. Pulled a code multiple cylinder misfire. My mechanic's diagnosis is bad valve cover gasket causing oil to seap into the spark plugs and bad timing belt, which I have not replaced at 150k miles. I do however know my fuel injectors do need cleaning, he hasn't ruled that out either. Have you pulled any code on it? I have read on engine knock sensor going out on some of these also. Hope this helps some.

Check fuel pressure and volume.
