Well I removed the EGR valve, checked the intake manifold port for being clogged, it's not. Checked the EGR Valve for proper operation it seams to work fine. I put evey thing back together. I started the engine to check for vacuum on the EGR, by placing my finger over the hose. I detected no vacuum at idle, then gradually increased RPM to 3500 where the engine started cutout like a rev limiter. During this time I detected no vacuum on the hose during an increase or decrease in RPM. So I think I have two problems 1. Being I have no vacuum at the EGR valve at any time, and 2. The engine is missing and is cannot go beyond 3500 RPM while sitting the driveway in park.
