There are most likely alot of vacuum leaks or the carb needs the mixture adjusted.

I have a 1978 Cadillac Fleetwood Brougham 425 with 4 bbl. carburetor. When my engine is cold, it stalls when I accelerated, whether starting from a dead stop or travelling at a fairly decent speed....


I would suspect sticking linkages. Spray all the linkage, especially on the choke side with penetrating oil and work it all back and forth.Make sure you engage and disengage the choke linkages manually through all its functions. Then spray it all down with a good lubricant like white lithium.
If you have the vacuum and heat operated choke then quite often that will gum up. Take it apart enough to get the piston out and soak it all down good with penetrating fluid.Wash the piston off and slide it back together. When it slides in and out easily, then give it a quick spray with lube and put it back together.

Stalling Issues


Was the TPS adjusted to 1.5 volts or checked for that voltage reading beforehand?

Hesitation problem


try cleaning the inside of the MAF sensor and do the following procedure as well.
Here is the most common cause of surges and stalls at stops and low erratic idle speed and rough idle, it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
