I'm at wit ends with this car seriously. Today my CEL came back on for the TPS (low imput), I've replaced the sensor, cleaned the throttle body, replaced a cracked hose, cleaned the IAC and STILL have issues. The car today didn't want to shift into 2nd only when I floored the accelerator did it shift, then when coming to and intersection I let off the throttle and the rpms dropped drastically to the point where it almost stalled. I am serious at a dead end. Someone please help me before I go out there and drive it till the motor blows up
