Had the car in for a post PI today and tech noted that the "vacuum advance" on distributor was not connected when the (previously bad) charcoal canister was removed. He teed into another vacuum line and connected the vacuum port. He noted that this will increase RPM's but will also help with acceleration.
I did notice a slight increase in acceleration but more so, the car is now idling at 1,600 RPM when warm. Seems excessive. Plus, I think that I noticed that the exhaust no longer "pops" when decelerating (which was kinda cool...yet slightly obnoxious). Thoughts? Thanks for educating this Newbie... |

@emerygt350 ....that 74 hose diagram above is wrong.
attached is another i found. this agrees with my jan 74. advance and retard lines correctly hooked to throttle body for advance and retard ports on throttle body. vac lines agree with 75 diagram (except no EGR yet). the diagram is marked up with amendments to charcoal can plumbing with Xs and revised line layout by @Starbear . he has an original 74 1.8, same as me, the diagram and discussion on charcoal can are in thread link below. some of the diagrams floating around have errors in them as a result of assumptions relating to earlier cars and possibly owner alterations/mods? http://www.914world.com/bbs2/index.php?showtopic=347951 |

That makes way more sense. Good.
