When the car is cold, it accelerates fine. I suspect i need a new thermostat because the car always stays at or slightly above the 1/4 mark and rarely gets over the 1/2 mark. So, when the car gets close to the 1/2 mark, it begins accelerating terribly. After shifting into 2nd gear, the rpms go nuts where they increase, stay constant, increase, stay constant, ect. this all happens with the gas pedal held constant for any somewhat-quick acceleration. the car accelerates in a jerky manner and is feels as if its bogging down. I've been told it could be the following: bad TPS sensor, bad MAF sensor, clogged cat, or a bad torque convertor. any ideas?

Sounds like a bad MAF to me. Had the same problems, replaced the MAF, but damn the car didn't like it at first
