I've been getting a code 32 intermittenly for awhile. I decided to put vacuum plugs on the EGR and the piece that that the vacuum line goes before the EGR(the silenoid maybe?) Well I didn't get a code for about a week and it came on again and the engine was a dog. Does this mean that the problem is in the silenoid or whatever that is before the egr and not the EGR it'self? I ran it for a couple of weeks like that and I only had a problem once. I also noticed that the engine revved much better and when the rpm's came down it did so much smoother than with the EGR hooked up.
