Hi guys ,
I just hope that someone could help us with the idle of my '75 2.0. I have the car for almost 7 years now and idle was always a little bit too high. We have been trying to correct this but it got worse instead of better. We changed the distributor to a 123 ignition, we changed all the vacuumlines, the AAR has been cleaned out and the idle screw is completely closed. The car starts at 1600rpm when cold and once it is warm it goes to 3000rpm and the idle stays there. The car pulls very well , a lot better better than when I just had it.

Update:
By the end of August we finally had some result. My mechanic took the AAR apart again and it's working now. But we still have a minor vacuum leak on the throttle body. Rpm when cold is between 1400 and 1600 but it drops to 1000rpm after a few minutes. I can live with that. I tried to find someone in Europe to fix the throttle body but no succes so far. I also found a new throttle body in Germany but it was so expensive... BTW, do all 914's have the same throttle body? In the mean time , I made some long test drives and everything works well.

QUOTE(slotty008 @ Oct 31 2022, 07:37 AM)  BTW, do all 914's have the same throttle body? No, they do not. All of the 2-liter 914 throttle bodies are the same, but the1.7 and 1.8 ones are a different size and sit sideways rather than straight up-and-down. I think the 1.7 ones are different from the 1.8 ones as well, but I'm less sure on that. Can you please ask your mechanic if he has a smoke machine? This has been suggested at least four or five times so far in the thread--for a good reason. It can help you find exactly where leaks are. Really, seriously. SMOKE MACHINE. Fill the intake with smoke and see where it comes out. You really really want to know where the problem is rather than firing the "parts cannon" at the engine and hoping the problem goes away. --DD |
