I have a 1989 Ford F150, 8 cyl. I had a similar problem where I would start my truck and it would die almost immediately. Anyway, I also replaced several things, but the thing that did it was the fuel pressure regulator. You don't say what type of car or truck you have. But it doesn't sound like it is like mine exactly. You could have gotten a bad fuel pump. How long since you had a tune up? How about spark plug wires, rotor? It could be misfiring.AnswerCarburator? Get a new car! AnswerMy friend had the same problem. He had to replace an air sensor. Or maybe you need some carb tuning. AnswerMy dad was having the same problem with our 95 Chevy Corsica. I'm about 99% sure it was a bad spark plug. Just as a thought.
My 87 Thunderbird had the same problem. I tried adjusting the idle, didnt help. I ended up replacing the idle speed actuator on it. Which is a sensor, located right behind the idle control bolt. This fixed my problem. If you are still having the problem, maybe consider the sensor.
Yes, it can cause low/unstable idle or die off at idle.
No, an engine idle RPM being not zero is not a problem. If the idle were zero, the engine would not be running!
Is it a stick shift?
A picture of an idle??? Idle is a state of operation not an actual part. As in, the engine is idling at 750 rpms. A picture of an engine at idle would look almost exactly like a picture of an engine that is running at 3000 RPM or shut off.
No it will not. It only controlls the idle of the engine.
ABS brakes should have no effect on engine idle, but a bad power brake vacuum booster would have an effect on engine idle.
Without having it checked for codes, It is impossibe to answer.
Engine vacuum leak.
There are a number of reasons why an engine would knock when you idle the vehicle. It could be your motor mounts. You may also need oil.
The idle control valve works by regulating the idle speed of the engine. The idle speed of the engine is usually controlled by the engine of the computer.
Probably not. They would have to be clogged solid not to let engine idle in which case the engine would not run at any speed. If they were semi-clogged the engine would idle but hold engine back from revving up.
If the check engine light does not come on when your truck dies it's probably the idle air control valve
because that's kind of a big engine
You might need to change the fuel filter.
check the soleinoid
I would clean, and possibly replace the Idle Air Controller. It regulates air to the engine to maintain an idle. It is bolted directly to the throttle body and will run you about $70 USD.
does the engine have a carburetor or is it fuel injected? A carbed engine has mixture screws along with a base idle screw, a fuel injected engine the idle is computer controlled.
The most common cause for an engine to die out, while idling, is the idle speed is set to low. You can adjust the idle speed with the fuel injector vital screw.
When an engine is in "idle" it is taking over by itself without any acceleration (or load) being applied. This the "idle RPM" would be the number of revolutions it makes per minute while running at "idle".
carb problems, adjust the idle screw and see if that helps
Incorrect fuel pressure. Plugged fuel filter.
Since it is starting from 0, the engine idle is low.
The idle speed control solenoid controls the idle of the engine when the air conditioning is engaged. Since the ac pump draws down the engine idle the solenoid increase the idle when the ac is on.
1. Engine Idle speed set too low? 2. One or more cylinders misfiring at low idle? (Spark plugs, plug wires, distributor cap or distributor rotor would be the common culprits.)
try replacing mass air sensor
