OK, so I originally had an issue with having to hold down the gas pedal to start the vehicle and then what I thought was idling issues after the engine warmed up. That was all solved by replacing the coolant temp sensor. In the process of figuring this out I replaced the IAC, PCV Valvle, and Throttle positioning sensor. Now the vehicle is extremely sluggish when trying to accelerate between 1000-2500RPM and then shifts up too soon. When trying to accelerate from a cruising speed it will not shift down unless you push the throttle wide open. Also, when I let off the gas to decelerate the RPMS drop to 1000, where as I would usually expect to see some moderate engine braking. No issues when giving the engine gas while in park. Is this a vaccum issue? Possibly a speed sensor issue? Or is it time to invest in a new transmission.
