My slant has been running good until lately. It is a 75 model, and about two weeks ago I flooded it one morning while starting it. After I got it started that morning, I noticed on the way to work that once I got it up to 60 mph, it would begin to sputter and spit when I opened the throttle further, like to accel to 65 or maintain speed up a hill. I figured I had wet the plugs with the flooding so I changed the plugs and wires that evening, and it seemed to run much better. Then yesterday, I flooded it again in the morning, and now it's spitting and sputtering at high speed when I open the throttle again. It seems to take off well, but once I get to highway speed, it will die out and spit back when the throttle is opened. I have checked the choke when it is warm and the choke is fully open. With the new plugs and wires, does this sound like a carburetion problem? The engine has a super six setup. As I said, this behaviour has started just since it turned cold and wet around here, and since I flooded it a couple of times. Any ideas? Davey

What is your timing set at?

Could your fuel filter be plugged or full of water?
Sounds like at high speeds where you need more fuel your not getting it, resulting in a lean pop. If nothing is clogged, check the fuel pump, it may be failing under load.

If you have time pop the top on the carb and see how much water is in there.
You may have to soak it up with a sponge or paper towel.

To be safe go buy some Heat (yellow bottle), it's alcohol and put it in your gas tank. That will help dry up the water. Don't use STP. It doesn't work worth a darn......

How do the plugs look?

my guess would be that whatever is causing the flood condition is what is causing the poor high end, not the other way around. The causes are almost endless, but start with what changed on the car not the weather, yes weather will cause it to run a "little" different but not like what you are experiencing. take a look around for vacuum leaks, and it might be time for a carb rebuild

It could be your ignition is on the verge of failing. If it is not firing, this could lead to flooding. The coil is one thing to check. It could have a carbon track that is allowing the spark to jump to ground. Or it could just be breaking down under load. I know the standard thing is to say a coil os either good, or is bad, but that is not totally true. Coils CAN be almost bad. Also, Mopar ignition boxes seem to be sensative to low voltage. Check out the voltage through your ignition system from battery to coil, and see if there is a voltage drop somewhere. My car was running poorly because the ignition switch had high resitance. Just like yours, it ran "OK" until the weather got cold.
