‘74 1.8L L-Jetronic Cold Start Low Idle, Mystery solved! Options

[Van B]

Ok fellas, here’s the run down Aux Air Regulator (AAR) and Cold Start Valve (CSV)/injector both work fine. Many of you have also been keeping up with my high idle issue that we figured out.

But yet, when the car is cold, i.e. room temp, I don’t get the high idle I should on start-up. Instead she cranks a bit and then lumbers to life. Idle lopes around 700-800rpm and then smooths out as it warms.

In all other aspects of operation, the engine seems to be pretty happy.

Mine came with a lifetime of records, even the original invoice! The owners manual, just like a proper manual, has all the torque specs for every bolt you’ll touch during routine service.

But now that you’ve given me a real service manual, it’s game on!
This is basically a new experience for me. I can remember my dad and grandfather building a 914 engine for my dad’s car when I was young, but I was too young to do much more than hold the wrneches.

Speaking of that screen, the owners manual gives a range of 7.4 to 9.4 ft lbs. I saw Ian said he goes to 9, but I’ll shoot for the low end if the treads are still good enough to stay tight at 8… maybe even some safety wire just for peace of mind.

This car will never hold a candle to my 996 in handling or speed, but it doesn’t have to. The experience of driving this 914 is so simple and pure I’ve started to use the term “motoring” again.
