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!

Yes, the vacuum to the fule pressure regulator. It should be drawing vacuum from the plenum. I think the decel valve is hooked to the same vac line. Even if it's hooked up, it may not be working properly. Check the pressure at idle and at higher rpm. I don't remember exactly, but it should be about 28 psi at idle and around 35 psi otherwise? If it is only running rich at idle, it might be the FPR. I don't know how common it is for the FPR to be bad, but if idle air bypass adjustments aren't having any effect, it could be this. Or as Scott pointed out, it could be the cold start injector. If it's the cold start injector, it will run rich all the time. |
