Running rich bad fuel injector?
Yes
Yes
In the exhaust manifold or exhaust pipe and is accessible from under the hood
Exhaust system.
Replace the sending unit, it is defective.
Is it water or antifreeze ??? It is probley condensation. If it is cold outside were your at then this is what happens. The exhaust system is cold and when you start the engine the exhaust heat flowing through the cold exhaust pipes makes the exhaust sweat. And it looks like water is running out. Engine is running lean. Needs richen up. If it is antifreeze it will be smoking real white out of the exhaust. And that would mean a head gasket is leaking coolant into the piston cylinder. That is the most common problem with a antifreeze leak causing white smoke. I have seen intake manifolds leak coolant into the cylinder head ( runner ) but it is rare that happens. I don't think you have a problem.
Too rich-unburned fuel in exhaust.
I'm Pretty sure the Z28 has to have 58lbs of pressure.That could be causing your problem.
the camaro would walk over the charger.
The engine.
Either weld or replace.
I think you are hearing pressure pops. Not a backfire.
