Teething Problems with 77 911s
 

I've just started to drive the car I hauled from Ohio to Alberta last week and am having some problems...

Problem #1

The idle hunts and often quits - I've scoured the board and this seems to be the mixture setting which I plan to adjust (for now I just increased the idle). While I was doing the idle, I noticed a vacuum port with no line connected (1st vacuum leak), it is on the throttle body right near the air box - any ideas what should be connected there?

Problem #2

The car sometimes won't start hot - fuel accumulator is my guess. It just cranks and when it does fire it stumbles at first.

Problem #3

The car sometimes won't even crank - all I get it the fuel pump relay clicking when I hit the key. Eventually it goes - starter solenoid is my gues from 15 years of working on Detroit Iron.

Any help or suggestions would be appreciated.

Problem 2: replace the fuel check valve first, its cheaper and it fixed my hot-start problems.

Problem 3: check/replace battery terminals, cables, and all connections. My SC wouldn't crank over either until I changed it all.

If you do some searching you will find some photos and some diagrams and exploded views showing how the vacuum lines are routed.

Your idle hunting is probably caused by a too rich mixture, although you should fix that air leak before you change the CO setting.

This should help w/ Problem 1.
