I recently had a new injector pump installed to
finally cure my lopey idle problem. WHAT A
DIFFERENCE !!!! My engine just purrs now. It
not only idles smoothly, but runs much better
at higher speeds and seems quieter. Ok, enough gloating. My question for the experts is this: Does the new updated pump have more output ? If so, how much more? Why else would it run so much better than with the old pump?
