1995 G20 Custom Van Spark knocking after EGR valve replacement
I am working on a 1995 Chevy G20 Custom Van with a 5.7L (K) engine. The Service Engine Light came on so I scanned it. Forgot the code number but it was "Bad EGR valve". I replaced the old EGR valve, (17087196 020 52N) with BWD 103D. Every since I did that, it has been idling rough and sounds like a spark knock under the TBI. Running too rough to drive. Was running fine up till the time the Service Engine Light came on. Any suggestions? Thanks!!!!!!
