L-jet running rich Options

[Ctrout]

I know that everyone here has D-jet but does anyone know of any L-jet gurus anywhere? My car has smelled like it runs rich since I got it. While doing some exhaust work this morning, it was confirmed by the black soot everywhere. I thought I read somewhere that these cars ran rich from the showroom floor. I have backed the idle adjust all the way out with no apparent change in the richness of the mixture. It did change the RPM to a point though. I read in one thread something about coming in from working on the car and smelling like I had been standing next to a diesel campfire. That's me!

A rich condition, beyond the scope of the idle mixture adjustment is ALMOST ALWAYS a bad airbox. Vacuum leaks may make it fail to run, but they won't make it rich. "Fallse air" going past the valve cover gaskets, the rectangular gasket on the filler box, the o-rings in the cap, all will prevent the car from starting, as the AFM isn't reading the air. A messed with airbox is usually a bad airbox. A reman airbox is usually a bad airbox someone has attempted to fix. Generally, what goes wrong with them, a sticking flap, doesn't get properly addressed in the reman process. Belly up to the bar and buy a new one! AFTER you've tested everything else, that is. In general, L-jet/Digijet FPRs go bad a lot, although the ones on 914s are an exception. Check for a good, even voltage supply to the ECU, check ALL THE GROUNDS, the valves, the dwell and timing, and the filters. The double relay won't affect the mixture, only the ability to run at all.

Hmm. Digijet ........... Anyone here ever given any thought to running Wasserboxer Dijijet on a 914? Seems to me it would be a drop-in ...................... The Cap'n
