If the egr valve is stuck OPEN - the Engine will run Very rough & idle bad - or not idle @ all-if the egr valve is starting 2 stick IT WILL TURN ON THE CHECK engine light-Sometimes U can take the valve off & clean them with a GOOD carb cleaner.
Yes, it can cause low/unstable idle or die off at idle.
You cannot simply turn an EGR valve off. You can clean it, replace it, or remove it, but you cannot turn it off.
Cruising down the highway, off idle.
The A/C idle compensator solenoid is not functioning. This should be located next to the carb.
Leave it idle.
Could be several reasons such as a large vacuum leak, a faulty EGR (Exhaust Gas Reclaimer) valve, a faulty MAF (Mass Air Flow) sensor,
Yes, it could.
Cheaper to turn it off.
You look for the button that you push to turn it on, then you push that button and hold it there for 3 seconds to go idle, and 5 seconds to turn it completely off.
I would look into a stuck open, or jammed Egr Valve.
Idle jet in the carb is clogged.
it has a low idle. Can also be a vacuum hose leak.
find out what is causing it to come on (by going to a shop) and correcting it.
Turn the idle down.
There is usually a solenoid that boosts the idle when A/C is turned on. If the car stalls when solenoid disengaged; the curb idle adjustment is off. Find the screw and give it a half-turn CW. Or, sometimes the end of the solenoid is the curb-idle adjustment . Put a wrench on it and try giving It a half-turn clock wise.
The EGR valve and the EGR sensor work together. The EGR gas temperature sensor is mounted near the EGR valve. The sensor detects the temperature of the exhaust as it moves through the valve. The information is sent to the ECM and in turn the EGR on/off time is regulated precisely and more efficiently. Any malfunction with the EGR gas temperature sensor will set off a code 35 ( Info taken from HAYNES MANUAL)
no its not normal..i personally have never heard of such a thing
There is a idle screw on the throttle linkage on the carb that you can turn to increase the idle speed and then hook up your timing light to check the timing.
You need to turn off the Overdrive switch.
I've been researching this as well, and have found others saying that some of these trucks aren't equiped with an EGR system. A truck without the egr will have a capped off spot right next to the Idle Air Control valve on the top-drivers side of the intake manifold. The EGR valve goes in this capped hole. My truck has the capped hole and no EGR.
If it is stuck open it will stall the engine at idle or run really rough. Stuck closed won't really affect it.
