Major Acceleration Problem... Advice Please
My small block has been running great up until yesterday. I had not driven it for two weeks started it up and as I started down the road the car was bucking, back firing and breaking up badly. I came home and replaced the rotor, checked the fuel filter, pulled the plugs and found 7 out of the 8 were wet. When I am up around 2500 RPM it seems to clear a little, but as the RPMs lower it get real bad. Before I had put it away two weeks ago I had added Lucas Fuel Treatment. Up until that time the car had run great. It feels as if I have water in the gas. Could this additive be the problem? I have an MSD systm on the car. I really dont know how to troubleshoot that. I am wondering if I remove the old gas if that will help. I have checked the wires and distributer cap. I am at a loss. Any help would be appreciated.
Thanks
Mike

You may have answered your question. Water in the gas. Lucas fuel treatment? I've never used it but a lot of them (fuel treatments) are formulated to pull water out of the tank by allowing the water to mix with the gas.
If you want to check for water in the gas, pull the gas inlet hose off the fuel pump and drain some fuel in a jar. Let it stand awhile and see if water settles out in the bottom of the jar. If it does, I would drain the entire tank and refill with fresh fuel and a fuel treatment that picks up water for a few tanks.
Of course, you have many other possibilities for your problem. This is only one.
