    Does the engine have a feed back carburetor or is it throttle body injection?

    has throttle body injection

    Is the exhaust side passageway under the EGR valve good and clear through to the exhaust cross-over in the intake manifold, or is it plugged up with carbon?

  • Albert Myers
    Albert Myers Sep 16, 2010 is all clear or carbon.

    no. It is all clear of carbon.

    Check the vacuum line to the MAP sensor for any damage, or if the vacuum line collapses when the engine is running. (Manifold Absolute Pressure)

Does it misfire under load like when you press on the gas peddle after slowing down then accelerate or at idle. When you say spark plug did you mean all the spark plugs?

Remove the EGR valve and look in the ports in the intake. There is a good chance they are stopped up. Good Luck.

SOURCE: i need to know how to install a egr valve in a 05

Once you are able to identify the EGR, you simply unbolt the valve and ant other obstaructing part. Clean its surface of carbon. Repalce the gasket if worn. Any sticky bolt/nut that you encounter could be removed by spraying some WD-40 around them. Also disconnect the negative wire of the battery first. Diesel do run hot, so get ready for some hard bolts to loosen.

Remove the throttle body housing on the top of the intake, it is a 90 degree tunnel like small piece held by 4 small bolts, turn it over and look for two holes, these holes are for the EGR valve flow, they are probably plugged up with carboned crud, clean them out with the tip of a screwdriver if neccessary to remove all the crud, once its clean reinstall it and reset your check engine light, hope this helps, let me know

I got a 1994 GMC Sierra it reads a Code 32 can't find out how to solve?

OBD1 fault Code 32 means that the EGR valve is either not working or the gas passages in the intake that deliver the exhaust gases from the EGR are plugged with carbon and sludge, this is one of the most common causes of a GM OBD1 fault code 32. Remove the EGR and see if you can blow compressed air through the gas passages under the valve, I will bet one of the two or both are plugged up.

Reading codes 13 and 32 smelles of gas 1992 gmc sierra 1500 k-model 350ci

13 is an O2 sensor circuit issue, 32 is the EGR-OBDI is not as precise as OBD!! but you should see if your egr is hooked up, or if there is a blown fuse for it-the O2 sensor might just be due for replacement, you could try to clean the codes first (disconnect the neg cable for 10 minutes) to see if they come back right away.

While you are checking things, make sure the fuel pressure regulator is not leaking or has gas in the vacuum hose that connects to it.

EGR Valve pintle intermittently sticking or not opening

possible but the code refers to the valve and or the solenoid to operate the valve
could be a loose / broken wire or bad ground connection
if it is that bad , replace the egr unit complete

CPoP0405 Chevrolet Exhaust Gas Recirculation Sensor A Circuit LowCode p0405 is EGR Sensor A Circut Low. I suggest you recheck your eletrical connections and make sure they are making good contact.

Engine won't idle,

ok code 32 is the EGR (exhaust gas recirculation) this does not mean that the EGR valve is bad right off, check it and see if it is stuck in the open position, remove the vacuum line see if it moves, it should not. It is supposed to open at highway speed to recirculate exhaust gases and burn them, if the valve is stuck open the engine will not idle because it upsets the air mixture too much, if you remove the valve and see its open, then replace it.
