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... |

Wanted to report back that my TB only has ONE port. All proper connections have now been made, car idles properly and that the extra connection off the distributor (shown in diagrams going to the 2nd TB port) has just been left open. I may eventually stick a 3" hose on it and let it "twist in the wind" as others have noted was the factory setup.
To repeat - my '75 1.8 engine has only the SINGLE PORT on the Throttle Body as dr914@autoatlanta.com stated was the case. Thanks again for everyone's assistance! |
