Great tips here.
But I wonder about the pintle. My Chilton repair book says the pintel should be cleaned. They have a picture on page 4-7 that shows the assembly of the EGR valve. It looks like the hole you are not spraying solvent in has a screw that allows to take the EGR valve apart.
Is it possible to get it back in correct function if I take it apart? I'm especially worried about the spring tension.
Electric cleaner should not dissolve the insulation, but clean out the dirt. Do you think that would lessen the risk of ruining the mechanism if it came into the hole beneath the valve?

Re: How To Clean The EGR Valve
I spray it in the opening under the "can" where you can see the pintle valve and use a dental pick to scrape the carbon loose. Tedious and time consuming, but with the right tool you can do a good job.
For a while now my car has been hesitating, just not accelerating smoothly and running rough in the 55-65 mph range. Cleaned out the EGR and she runs much better. One of the easiest fixes I've ever done on this car. The images sure helped.
Such great info here. I've done the RPM/ Coolant Temp/Volts mod on my 94 Concours as well as cleaning the Throttle Body. Today we were out running errands and the car started running very rough. The cat was also getting hot. Stopped by the parts store and picked up an EGR Valve gasket and a can of Brake Cleaner. Pulled off the EGR, cleaned it and re-installed. Car is running smoother and has better throttle response than it ever had.
A big "Thanks" to this forum and the people that contribute to it.
A new EGR was $177-275 depending on the manufacturer. $7.49 for a can of cleaner and gasket worked out much better for my budget this week.
