You would notice if you were running on 7 cylinders...maybe you need a different mechanic. Do a search here on the boards and you will find tho that a lot of people dont like or have had problems with Accel. Myself included....

unplug the #7 injector and see if it runs the same. if it runs crappyier its probably not the source.

you need to give more information on your problem.

Perhaps you could swap in, a known good injector,
just for testing.

If you have headers just spray water on the header with the suspected dead cylinder. It should not burn off very rapidly as the ones with the live cylinder will. This will not work with cast iron exhaust manifolds. Allen
