This is the final segment in a 4 part video on how to rebuild a Corvette C4 throttle body. In this video I demonstrate how to install the a new idle air control valve (IACV) as well as new gaskets for the throttle body assembly. I also discuss after market screw replacements that were damaged during the tear down ( see Part 1). What is not shown is how to reinstall the throttle position sensor (TPS) we removed in the first video but it’s easy enough (see Part 1). If you have any questions, don’t hesitate to email me or post your comments on this thread.
