Misfiring is often due to ignition system components. "Decarbonizing" is Chrysler's version of using "SeaFoam" in your engine. In fact, the product is basically the same, only more expensive. It has nothing to do with misfiring unless your spark plugs are coked up.

A consistent misfire in your engine should be diagnosed by checking fuel and ignition system components and doing a compression check on the engine cylinders. If the cylinder compression numbers aren't fairly even, or are lower than they should be, that would explain the misfire.

I'd bet you either have fouled injectors or faulty wiring.

It seems to be more and more common since the induction of OBD systems that "technicians" rely entirely on the OBD system and throw parts at a problem, without applying proper diagnostics to actually figure out what's causing the issue. You seem to have fallen victim to this exercise in cash-tossing.

If you are saying it starts and then dies, have you checked fuel pressure again ? Could be the fuel pump relay.

SOURCE: 1962 Ford Falcon wont run unless choke is partially closed

check the float level setting
it presents as a partially blocked main jet circuit
there could be corrosion in the circuit that the cleaning agent has not removed
it may be necessary to remove the lead blocks for the drillings to physically remove the blockage
if you look at the drillings and passage ways of the carby you will notice what appears to be plugs inserted where it has been necessary to use a drill to make a circuit for the fuel and air flow
these small plugs are lead pellets similar to shot in a shot gun cartridge that are inserted into the hole and pressed to expand and act as a plug
consider taking the carby to an accredited carby overhaul specialist shop where they can remove/ replace these plugs and test the carby on a machine for correct adjustment and settings
