Adjusting 308qv fuel distributor

12-10-2004, 10:14 AM

I have 2 lean cylinders at idle as shown by testing each cylinder. At constant throttle I can feel the slightest lean miss. Am I ok readjusting the fuel distributor at idle, assuming these two cylinders are also slightly lean @ 3000rpm? I have no way of testing at 3k with slight load. 1984 308qv.

Are the injectors new? If not, you probably have two that are dirty. Run some Techron and blast around and re-test.

Yes, new injectors & injector seals, and that helped a lot,
then I tested each cylinder.

Ok. I know that you can tune each cylinder at the fuel distributor. JR, or someone else, will have to respond with the proper procedure.
