No,
You can try to clean it. Remove the valve, and clean between the valve and it's seat. After cleaning it, pour a solvent (gas works well) and see if the gas leaks past the valve. If it does, replace the valve.
A rough idle when cold may also be caused by dirty fuel injectors. First step to clean the injectors is to add Chevron Techron fuel injection cleaner to the fuel. Use double the strength listed on the bottle. Don't waste money on other brands, they don't work well.

Rough idle 95 astro van, I did a full tune up , plugs,wires,cap, rotor,air filter,and fuel filter and cleaned egr vavle.


I actually had to replace my EGR valve and the gasket. I clean the valve well and reused both. I don't think the gasket sealed well enough though. So I went ahead and got a new valve, gasket and changed them. It runs a lot smoother now.

Perform a valve clearance inspection and adjust if necessary. Tight or sticking valves will cause a misfire or rough running concern. Note: Perform valve adjustment when the engine is stone cold. 4cyl: INT 0.26mm EXH: 0.30mm (V6 engine are hydraulic and no adjust necessary.) Also check for a sticking or stuck open EGR valve. For diagnostic purposes only: Remove the EGR valve. Place a business card over the EGR passage and bolt the EGR valve back on. This plugs the EGR ports and if the misfire goes away the EGR valve is partially stuck open and is defective.
Check for low fuel pressure. Check for low compression. Check cam timing. Check for a weak ignition coil. Also don't over look the possibility of worn or broken engine mounts which cause excessive engine movement and engine vibration. -hope this helps

1995 Chev S10 4.3L V6 rough idle and under power


This make/model has a chronic problem with EGR clogging. If you have a dashboard indicator showing "check engine" most likely it is a trouble code indicating and EGR (exhaust gas recirculator) valve problem. Symptoms are rough idle, and surging and stalls.

What happens is sediments from the exaust manifold get sucked up into the valve when it opens, then stick in the valve and keep it from closing. When the valve is open when it should be closed, the engine runs very rough.

I removed my egr and then dislodged the sediment (pea-sized debris) and then re-installed the valve. Three days later, the same "check engine" and same rough idle. I must have did this at least three or four more times.

What I found that gave me a permanent solution was an aftermarket filter gasket that keeps debris from clogging. I don't remember the name of the product, but a search for "EGR filter gasket" may lead you to the product.

Install the gasket between the EGR and the exhaust manifold and you should be good to go. Note: on 1995 and newer models, disconnecting the EGR from the wiring harness (common on R&R) may require the computer to be reprogramed.

sounds like a problem in the egr valve or the porting through the egr valve or maybe a vaccuum line that has something to do with monitoring it. make sure there are no vacuum lines near it that are leaking and is there a difference in the idle that you may notice.

Rough idle only when engine is cold


check to see if the vehicle has EGR valve most of them are either elecrtronic or vacum controlled disconnect it and start it check and see if this smoothes out cause it sounds like the valve is staying open while the engine is cold if thsi solves the problem replace the valve.

secondly take a small screw driver aor a tiny hammer and tap the valve while the engine is running if it smoothes out replace the valve the valve is carbon filled and needs to be changed .
