Replacing with new parts made no difference...plugs/wires, catalytic converter, fuel pump/filter, 3 sensors-cam, crank and oxygen.
Put your hand over the tailpipe and have someone attempt to start it, you should feel pulsing , if not you have a plugged exhaust, it happens! All the best,,

Before all this work was performed and money spent on parts, was the PCM checked for any DTC's?? If so, what was the read out?

Year make and model ? Have you checked base fuel pressure hot and cold ?
Some of the components you replaced only adjust fuel mixture, while the MAF and TPS would directly affect acceleration. If any of the sensors were faulty you should have trouble codes. So fuel pressure and volume are often suspect. You could also use starting fluid sprayed into the intake to verify the problem is lack of fuel.

Fuel injectors should be next on your list of things to check and replace. You might also check your oil to see if it has turned any abnormal color. This will let you know if you have a liquid leak in the engine. When you removed the old spark plugs were any of them wet?
Testimonial: "I did clean injectors but no help and had 2 plugs a little wet just don't Minos what else to do, Thanks"
