I would start by changing the fuel filter. Run some injector cleaner through it. And check for more of those rotten lines. You can check by spraying a little starting fluid around the vacuum lines. Be careful though. Its flammable. But the engine should speed up if you have a leak.

My '91 GMC Jimmy suddenly died like it was out of gas. It restarts, but idles rough, sputters and pulses. Plenty of fuel comes out of the injectors, but it wants to stall and die.


start at the beginning fuel pump pressure at the pressure regulator then look for ignition problems , check mass air flow sensor if equiped

Rough idle stalling, only runs when pumping gas pedal


Either not enough air or fuel. Check the air filter and gas filter. Also could be the exhaust system Catalytic converter clogged. No air out, no air in.

Starts dies


an alternator won't stall your car, the battery provides power to keep the spark going. It sounds like you could have some bad fuel, if you're able to run the throttle manually with your foot and keep it going that would indicate idle control. but if it stalls still when you are giving it gas. I would guess a fuel supply issue, either water in your gas, or fuel pump. Good Luck.

1983 s10 blazer low rough idle and trys to die when starting have to give it a little gas and put it into drive real quick then when slowing down keep foot on gas pedal as i also slow down with break pedal


Could be several things, a vac leak, dirty throttle body, or faulty idle air control valve.
The computer controls idle speed by how much air enters the throttle body thru the valve.
Usually a vac leak would speed up the engine unless it is causing the rough idle.

Sounds like a large vacuum leak,low fuel pressure,fuel pressure regulator failure, idle air control valve stuck open,plugged fuel filter.Also check for good consistent blue spark at spark plugs or jumped timing chain.Hope this helps!

Try changing the fuel filter. You may want to consider a Weber carburetor conversion. That Asian carb is old
