Check Engine Light Due to Engine Vacuum Leaks on Mitsubishi Galant

The Check Engine Light may illuminate due to one or more engine vacuum leaks. Our technicians tell us these leaks can be caused by damage to seals and/or vacuum hoses as a result of to much ethanol content in the gasoline. Affected hoses and seals must be replaced to correct this concern.

Car runs fine given her age until you're sitting still. Car idles really low and kind of acts like its going to die. Driving off again it runs fine. Check engine light popped on after a very slow drive thru during a McDonalds charity promotion. The car has never thrown a light warning until this time and I've had the car when it had 22 miles on it. I'll have the shop check this tomorrow. Thank you for this website!

Car Idles between 2500 and 500 rpm upon start up. Engine vibrates or bounces like it is being suffocated. Car does stay running while in park. However when put into gear it stalls repeatedly.

Engine light on, diagnosed as vacumm leak. Car idles low, esp at stops. This is not noticable while driving, only when stopped.

When starting, engine vibrates or bounces like it is being suffocated. While in park it stays running but as soon as out of park, it dies out. After restarting, I can get it going, and out of the parking lot but it is very bumpy, "airy" - sounds coming from the engine. Eventually runs smooth when up higher speed. No more issues at stops at lights or anything, usually just starting the car after a drive or in the mornings before having driven.

I start the car and after so long or at a stop light it does and all the lights come on sometime it will start right back up and will die again
my battery light and brake light have been coming on/off for past 3 months and everytime I take it to get a diagnoises nothing is ever wrong. Then the other day the dash board went crazy lights blinking on/off and then just went completly out. And 5 minutes later I'm stranded. The car stopped and is now going to heading to the shop. What is going on? I WILL NEVER BY ANOTHER MITSUBISHI!!!!!!!!!!!!!!!!!!
At the moment the check engine lights keeps coming on.
