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.
Thanks
Andy

Yup. General concensus is that the 3800 and Bosch don't get along. I've got AC Delcos and cheapo NASCAR Select wires, and she runs great.

The AC Delco'* work great, but if you don't mind spending alittle bit more money, I would suggest going with the NGK'* along with some Taylor or MSD wires.

The only time my Bonneville seems to miss, is when it is in overdrive and the torque converter is locked up running around 50 mph. Other than that it runs great and gets good mileage.
I think I will go with either the NGK'* or just the plain old AC Delco'* and see what kind of a difference that makes.
Thanks for all of your replies
