Just replaced the egr. I think I'm going to try and just block it off. Though talking to a couple people they said that it might not be the problem. Now that I'm in a hotel for the night and not on the side of the highway in scorching heat I can describe it better.
I made it about 120 miles, after slowing down for construction I went to accelerate slowly and the tach started surging basically but with no power. Pulled over, the car started right back up. Kept driving, about every 5-10 miles it would do it again. The rpms kinda dance around 1000, if I put it in neutral and pump the gas a bit sometimes I can save it from dying, but the rpms will kick to about 3000 then slowly come back down. I stopped and bought a new EGR, made it about 50 miles and it did it again. Stopped for about 20 minutes, put my stock PCM back in, thinking something might change. Drove another 10 miles into the next town with one small hiccup. The car idles just fine, no problems at all with that.
Here's what I've figured out so far. It really only happens when the car has been running awhile and the engine has a significant amount of heat to it. My coolant temperatures are right where they are supposed to be though. Currents thoughts are possibly the crankshaft position sensor? I don't believe it is a fuel problem. I have a new pump as of 6 months ago, and I have pressure in the rails.
