I have a 95 mitsubishi 3000gt sl. I am Haveing major accelation problems. Press the gas and the car trys to die. I have done sone work to it. Car wouldn't crank so I checked everything from replacing the fuel pump, spark plugs, wires. Come to find out the eci fuse was blown. Replaced that. The car turned over finaly. But when I started up, it idles really low and the engine loped, pressing the gas would cause the car to not excelerate. It would go from 750-900 down to 500 then about die if I didn't feather the gas. I figured it was air. Listened to the engine and it sounded like the intake was sucking in alot of air. I just replaced the intake gasket yesturday. And nothing changed really but the sound of air is almost not there. I unplug the Mass Air Flow sensor, and press the gass a bit and it starts idling right. Then I let it run like that for a few minutes and plugged it back in and it dropped in rev but didn't try to die until I pressed the gas. I am at a loss on this car. The mass air flow sensor is a 105$ and I was wondering what else could cause this issue. Thanks in advance.

 

Throttle positioning sensor?
