What is the best way to clean the EGR valve?
I have a 93 V6 running a little rich and hesitating some under acceleration.
I am open to other things to check. Cap and rotor and plugs and wires and fuel filter are ok. No obvious vacuum leaks in intake / maf.

Thanks,
Kevin
on the other hand, I just rebuilt the rear end after the outer pinion bearing let go and all is well again. I am on a short tune up craze here.
