I have a 95 Mitsubishi Galant that I use for work.
It used to be that it would simply stumble at lower RPM's but when I got it above 2k it would smooth out and accelerate just fine. But now, I can barely drive the thing when it gets to Normal driving temps.
The car idles fine, 90% of the time. Sometimes it drops about 400RPM and sputters but jumps right back to about a 1000Rpm idle.
The plugs, wires and air filter are 2 months old, the cap and rotor I replaced yesterday, along with the fuel filter.
I checked the wires for arcing, but saw no signs.
The check engine light comes on, but not when this issue is present. For the last 4 days the check engine light has been off, but the issue has gotten worse.
I can hear the fuel pump working before I turn the key to start the car.
Tried some commercial Injector cleaner on a whim, nothing.
Checked the Mass Airflow sensor, it looks clean to me.
Any suggestions?
