SOURCE: I have a 2003 GMC sonoma with a 4.3L Vortec V-6. I

The mid-02 and up do not have an EGR valve. GM redesigned the 4.3L and introduced it in the middle of the 2002 production run. The fuel injection spider, EGR system, knock sensor type, and a few other "refinements" were made at that time.
Have a scan tool capable of opening and closing the related solenoids in the EVAP system to verify that they were working? Did you check the engine for smoke in the intake that would result from a malfunctioning EVAP purge solenoid? If the purge solenoid were stuck open, then it could act similar to a failed or failing EGR valve.

Have a shop with a dyno, do a Drive cycle to refine the problem. Here is a link on what a drive Cycle is. http://www.obdii.com/drivecycle.html

Good luck and hope this helps. You can always go to Auto Zone and have them scan the truck for any codes, it just may time for a tune up. Not know how the truck has been taken care of before you, try add Marvel Mystery Oil to the engine 1000 miles before it's oil change. That should clean up any internal dirt and do not use any engine oil flush, that just promotes oil leak.
Keep me posted on how things are going, I also found that the only thing the GM 4.3 like is the OEM distributor cap and rotor, every after market gave me a rough running engine.

SOURCE: How to clean EGR valve passages in 1993 Isuzu Trooper DOHC V6

You have to the EGR valve (sometimes the Intake manifold to EGR Vlalve line also). After you remove it take a drill bit the about 20 % smaller than the actual hole of the outlet side and rotate the drill bit with your hand to dig out the carbon. Aditionally the line coming from the intake manifold to the EGR valve will clog near the connection to the EGR valve. I use either a single piece of copper wire or the wire that you would use to tie ribar together to clean the line. When your done cleaning take a piece of vacuum line and connect it to the diaphram side and **** on it... then plug the line well with your thumb. Grasp the valve and blow thru it... Air should blow thru it freely. Remove your thumb from the vacuum line and try blowing again.. No air should pass thru the valve.
Then reinstall the valve and start the vehicle with the vacuum line disconnected (but blocked off) Use another piece of vacuum line connected to the diaphram again and **** on the line.. The vehicle should die or run really bad. If it does this then you cleaned it correctly.

96 sonoma running too rich with p1406 code


P1406 EGR Valve Pintle Position Circuit Fault
This code is usually caused by carbon buildup in the EGR valve. The carbon deposits prevent the valve from closing completely.

After removing the EGR valve, clean the pintle seat area of the valve and the corresponding passageway in the engine.

or simply replace the EGR valve.

Hope this helps!

My gmc sonoma (1996) 2.2 wants to stall when slowing to a stop and i cant figure out if its the IAC or the egr system do you have any suggestions?


the iac, when you start the truck cold does it idle up and then slowly drop? remove the egr valve and make sure theres no carbon holding the valve open, then drive it with the vale hose dissconected and see if it stalls, if it doesnt stall with the valve hose removed and pluged then i would say the egr valve, but if it still stalls then it may be the valve, also make sure the throtle body and the plate is clean, use old tooth brush and some crab cleaner to clean, do this with engine off, try these things first,

I have a 1993 GMC Sonoma that shifts hard from 1st to 2nd gear but good in all others and when u put it in gear i goes in gear kinda hard it is an automatic with 120000 mi


my friend you are having valve body problems, the 1-2 shift acumulator valve is probably stuck, you have to service the valve body or replace it
