i'm currently running autolite ar3910 plugs in my car that are fouling out on me.....i'm prob gonna end up running a slightly hotter range plug to help but here is my question......when my battery is diconnected and then reconnected and the car first fires up i have about 55-60 fp and after running for a while it goes back to 45-50 where its programed to be....its a aeromotive afr and i was wondering if i can almost trick my computer to lean it out some with it by increasing or decreasing the pressure......my inj where all cleaned and checked to be good...new gm o2's.....is this the regulator doing this....will a higher heat plug help at all...i was running ngk but those things last about a week at a time b4 they are to fouled to start the car...the autolites wor great as long as the car fires right up first try....i know this was long but any insight would be helpful here
