Does this sound like I need to replace the Crankshaft Position Sensor?

Hi and greetings as this is my first post. I have a 2000 GMC Jimmy/Envoy and it has 172200 miles. I just replaced the following, plugs,wires, cap&rotor 2 02 sensors, and when I go to heavy accelleration from a stop it sputters like cuts out,doesn't die but I have to back off the throttle to go. No engine lights on either,does this sound like the Crankshaft Position Sensor? Thank you for the help.
Also another issue I have is when I press the Tow/Haul button it seems as if the transmission disengages and it just revs the motor with no motion if pressed while I am driving in D or do you activate any certain way. Now this was happening before I had two shift sensors and the accumulator replaced a few months ago, i have been scared to try it out.

I know this is old, but no it doesn't sound like this. Sounds like a faulty distributor cap to me. I just went through this, my 2 brand new Autozone Caps were crap. Replaced with AC Delco and problem solved. Evidently Autozone is the worst one out there.
