Assuming that everything is right. Where is the idle adjustment on a 1975 Porsche 914 with a 1.8L engine with l-jetronic. Car is absolutely stock.

Hi Steve,
I'm also a newbie with 914 (1975 1.8L), I got mine last Aug. 2011. Anyway, I agree with Capt and other members of their comments and suggestions. Just to give you also my side, my teen was not running since 2003 from previous owner (my neighbor around the block), so that is 8 years non running teen. What I did first is to replaced battery, replaced all vacuum lines, replaced all fuel lines (except fuel lines along the tunnel), drain gas tank and after that, the car already running but the idle only good for 1,200 rpm and if I lower it, it will die. Until now, I did not touch my distributor cap or adjust anything with it. So after driving the car for a while, I tried to look for some more issues to lower my idle below 1,000. So yes I did find one thick rubber hose attached to the intake manifold just beside the cold start valve that was kind of loose, so I replaced that and now the idle stays below 1,000 and does not die anymore and it start better even in the morning. Still planning to check or adjust the valve which I assume needs to be adjusted. In regards to the idle screw, I had a hard time adjusting the idle with that screw until all the vacuum lines are perfect. Thank you and God Bless! Noel |
