99 chevy malibu,

New exhaust with converter, plugs, coils, map sensor, gas tank fill tube, & cap

The car will be running fine & it will start stalling & running like it's running out of gas, after it stalls
I'll put the car in neut. & crank it if I hold it to the floor it will start up & some times it will continue
to stall & sometimes it will run fine.

We have noticed that the exhaust is very smelly during this process.

Could be a few things Mike but what i would do first is
a fuel pressure test to check your fuel pump,
Should have a pressure value of 41 - 47 psi, Key on engine off (KOEO)
Just a little tip, if you just changed your plugs i hope you didn't use Bosch plugs
that will give you that same problem believe me see it so many times in my shop .
Post back after you carried out the fuel pressure test .

Thanks for your reply, the car is at a repair shop now they have checked fuel pressure it is a little
low. They were able to get it to fail & said that it lost fuel pressure, they installed a new fuel filter
& have been driving the car, the fuel pressure has not dropped but is a little low.
Thanks I'll keep you updated.
