Ok guys, not sure what to do.
Recent acquisition of a '76 912E #483. As most of you know, it is powered by a 914 2.0 with Ljet induction. Motor runs well, but idles high and runs warmer than expected, so I am thinking vacuum leak. Of course will go through ignition first, since 90% of FI problems are ignition. (IMG:style_emoticons/default/smile.gif) Chased FI problems on my 1.7 djet for a couple years before I gave up and put on some EMPIs. Been running awesome for years now! So.... Thinking of spending a couple of hours tuning the ljet and replacing all vac lines, but also thinking of just taking the plunge and putting on some EMPIs. Thoughts ? Don't care about resale; car is going in dd rotation and will get DRIVEN!! |

Running too hot may mean your timing was advanced too much to mask the vacuum leak. Ljet is very simple, it works or it does not. Replace all the vacuum lines, oil cover seals and check the plenum for leaks, and the manifold to head connection for leaks.
Replace the injector seals. Timing, Clean your distributor advance plates, get rid of the 40 year old grease, it's like glue when hot. That will also make carbs run like crap. Set the timing per the book specs. If you can't keep it running with the timing set properly , you Do have a vacuum leak |
