What should I be looking for when I get code 33 - EGR Control Pressure/Baro Sensor Circuit High. Had the code about a month ago and I cleared it out. It's been good for awhile, but has now come back. Help me out here, please!!!!

There are some posts out there on EGR's. That little valve has a tendancy to stick. Some have cleaned it and it works. May want to check vacuum lines, 'noids, and the wiring to the sensor.

Check the connection to the baro sensor on the firewall near the hydro-booster.
Mine had wiggled loose and caused intermittant code. I put some di-electric grease on the connection and tie-wrapped it tight.
