Re: Fuse block power supply
Well its been 4 days with no issues. Runs like a champ.
I went through everything again. Testing, tracing wires, vacuum lines etc. I finally pulled the egr valve again to bench test. Held vacuum perfectly. Plunger was fairly clean of carbon but I figured to clean it anyway. I found out that the plunger valve that closes off exhaust gas would occasionally leak. I made a block off plate and gasket and installed them. I changed the pcv as well. Hasnt skipped a beat since.
I think what was hsppening is that when coming off throttle it would randomly stick open a bit which caused both a vacuum leak and exhaust gas in the cylinders which couldnt be compensated for.
Time will tell if my theory is correct. I'll keep you updated if it changes but for now I just want to thank all of you for your help.
The people on this site are great.
Jeff
