What are the best plugs to use on a 3800 (non SC)
I recently replaced my plugs and wires to correct some bucking and snorting symtoms on my 96 Bonneville.
What I notice now is that it still misfires a little when I put a small load on the engine after the TC locks up at around 50 miles per hour. Now it is miles better than it was
before the plug and wire replacement but it still misfires a little.
The plugs I used were Bosch super plugs. These look like conventional plugs, (they don't have the extra electrodes)
Is anyone else running these plugs or have you had problems with them? Are the AC plugs better suited for this engine?
Any help would be appreciated.
