Check for a major vacuum leak.
IF IT IS A MANUAL TRANSMISSION CAR, THEN IT SOUNDS AS IF YOUR CLUTCH IS BAD/WORN OUT.
I have a 1998 olds Intrigue and mine started doing that it was the crank shaft position sensor
if its a manual then it could be three things, clutch cable or throttle cable, or IAC (idle air control valve) but if its an automatic it could be throttle cable or IAC.
put more in or get a new car
I let my car idle for 10 minutes.
If you mean each time you engage car in any gear forward or reverse & it immediately stalls - you have a bad torque converter. Start engine, put foot on brake, put car in NEUTRAL, if it DOES NOT stall, but it does stall if you repeat this test when you put car in drive or reverse = bad torque converter - It's called a "stall test"
700 to 750 rpm is normal. if the engine stalls, you may have to replace the IAC (Idle Air Control) Motor. they get stuck.
outboard motor will start and idle, but dies out under load
You are going to need to stop at the Ford dealer and put it on an engine analyzer for this one.
Carb needs curb idle adjusted or rebuild.
Check the idle air motor.
check the brake booster vacumme hose,its the hose than runs from the intake to the brake booster. if its leaking air the car stall when you hit the brakes or has no power
