Well after replacing the manifold pressure gauge and sender, checking for leaks
and verifying none I am about at wits end. The new gauge and sensor work
but now I am showing 3.5" low at 1500rpm and never reach 20" at max
throttle.
The only thing I have not checked at this point is the fitting on the number 3
cylinder for a blockage. I didn't because the gauge was reading fine until the
sensor went bad. Hopefully will get good results cleaning the fitting.
