    No codes,no check engine...mechanic did a fuel system cleaning but the results were more stalls (he refunded the bill for his work).With no codes,he is lost.

If there are no codes, it might be a bad head gasket with variations of pressure in the cylinder depending on how warmed up and how much of the exhaust fumes are going between cylinders.

It will wheeze.

Why did my speedometer stop working and within minutes my 02 Cadillac Sts stalled and would barely accelerate?


The speedometer and odometer gets a signal from the speed sensor in the side of the transmission where the speedo cable once was.
The problem could be the speed sensor, or something in the wiring, or in the instrument cluster. Or it could be that the transmission is failing internally.

My rpm's raise and drop at a stop and engine stalls when i turn ac off


We need to know the model, year, engine size, and the actual trouble code to really help you; but I provide some generic tips at the link below. Do not replace the sensor until the problem is properly diagnosed. O2 sensors rarely cause stalling. Get the computer scanned and ask them to find any historical or pending trouble codes. Write them down and post them here.

My 1996 GMC jimmy wants to stall when I come to a stop. The RPM gage goes up & down then drops below 1000 RPMS and stalls.


I would go down to your local auto parts store and do an alternator and battery test. It sounds like at low rpms you are loosing volts. When you apply the brakes you would be supprised how much power from the engine it takes. You could also be loosing oil pressure. Check your oil level. When your engine drops low rpm, the oil pressure drops and shuts down the engine.

RPMS drop wants to stall somtimes and hesatates in


I'd be curious to the miles on the engine, possible worn rings, poor compression. Start with basics first, be certain there are no vacuum leaks, next look to your fuel system; possible failing fuel pump (low fuel pressure) dirty fuel filter? (I'd start with the filter first, cheapest fix if it is the issue) other concerns could be injectors, plugged or failing (poor fuel spray) run a fuel systems cleaner for several tanks see if it will improve; but change that fuel filter first. Also the volts dropping off would make sence if the engine RPMs drop way off, too slow of a speed the alternator will make little if anything.
I hope this may have helped,
Tom

98 S70 RPM's jump up then stall when car is stopped


does this model have an ETS on it? Electronic throttle system. I could need a new throttle body. Sometimes the software goes bad and it will give the symptoms you described.
