1993 Chevy Blazer 6 cyl Four Wheel Drive Automatic 177000 miles
Ok I have code 43 and ive replaced both knock sensors and the wiring to the one on side of block. Getting 4.77volts at connector with sensors unhooked, replaced ECM and prom still code 43 terrible gas mileage 10mpg on highway, no other codes, recent tune up and CPI EGR not clogged I cant get it back to regular timming this code 43 is killing me. Is the knock sensor in the rear next to distributer cap different than side mounted one for resistance, side is 8.3 and back is 9.00 im stumped is the Electronic spark control module located in the ECM?
