Ok so heres the deal with this Thunderbird I got. My grandpa passed away in Nov and right before that in Oct last year he gave it to me.
I had to have it hauled home from Texas and it sat at my uncles all winter.
I got it home last weekend and its got a few codes that wont go away.

p2106
p2111
p2135
2104
P2104 is an OBD-II generic code for the engine control module (ECM) detecting a major failure in the throttle actuator control (TAC) system causing the ECM to go into failure mode forced idle and limiting the engine to an idle RPM limit only. The throttle will not respond to any increase in throttle.
2106
P2106 is an OBD-II generic code for the engine control module (ECM) detecting a major failure in a system causing the ECM to go into failure mode and limiting the throttle actuator to limited power.
2111
In this case the code definition is fairly self explanatory. The throttle is stuck open. It’s important to understand that the PCM (Powertrain Control Module) uses a sensor to monitor the position of the throttle plate. The throttle plate may actually be working correctly but the sensor may have failed and would be reporting the incorrect posi(tion to the PCM.
2135
The Accelerator Pedal Position (APP) sensor is an input to the Powertrain Control Module (PCM) and used to determine the amount of torque requested by the operator. There are 2 pedal position signals in the sensor. Both signals, APP and APP2, have a positive slope (increasing angle, increasing voltage), but are offset and increase at different rates. The 2 pedal position signals make sure the PCM receives a correct input even if 1 signal has a concern. The PCM determines if a signal is incorrect by calculating where it should be, inferred from the other signals. If a concern is present with one of the circuits the other input is used. There are 2 reference voltage circuits, 2 signal return circuits, and 2 signal circuits (a total of 6 circuits and pins) between the PCM and the APP sensor assembly. The pedal position signal is converted to pedal travel degrees (rotary angle) by the PCM. The software converts these degrees to counts, which is the input to the torque based strategy. The PCM flagged a concern indicating that throttle position voltage PIDs TP1 and TP2 disagree by more than a calibrated limit.
I put a brand new battery in it and throttle position sensor on the manifold side.
Itll start and idle and codes come right back. Itll rev up and drive if its cold. Once it warms up gas pedal goes unresponsive and will not rev up.
Last night after I put a battery and tps sensor in I cruised around town for a bit (i live in a small town about 450 people.) then parked it in front of my garage and left it running. Went back about 20 min later to move it and I was gonna go wash it but the gas pedal was unresponsive but car was still idling.
:thinking: I dont get it.
Gonna check gas pedal side TPS sensor tonight but I dont really want to throw a bunch of parts at it.
If I dont get it sorted out soon itll have to sit until after house is shingled and 2 post lift is in.
Thoughts? Ideas?
