Hi, Just bought a really clean '89 Blazer. It has a newer rebuilt motor that is TBI. I bought the truck and the guy was explaining to me about the cam it has in it. He said that he usually runs with the EGR unplugged because it runs smoother. So today, I plugged in the EGR to see what happens. The truck idle's fine. I notice a little hesitation when taking off. The big thing is.. when I am driving and I am coming to a stop, when the truck is idleing down at a low RPM, all of a sudden it will act like it has a monster cam in it. It will lope and act like it's going to die but it won't. Weird thing. Any idea's ? Thanks.
