95 Z28 surging at idle and while driving
I have a 95 z28 that surges at idle. Some days it runs great no issues. SES light is on. I have replace the air temp sensor in the elbow, both temp sensors and the opti. while driving it feels like loss of power. Anyone have any ideas? Thanks

Had the same issue with a 2003 Buick Regal 3800 V6 - Turned out the tube that runs up into the manifold from the EGR Valva was plastic and melted and coolant was getting into the throttle position sensor which would cause sudden acceleration.
