Car won't start up, just cranks, motor comes on and boggs back down and dies! cel and eml are on....and my motor is hot as hell!! i just got done replacing shift cables a week ago and the car ran fine......its been hot recently and i've been blasting the a/c, which makes the car run slow as hell and it sounded like it worked my motor real hard. anyone ever had this issue before?? previous owner had the throttle sensor replaced a year ago, u think its out already?? arrggh....i gotta headache

Mini DTC P0638 - Throttle Actuator Control Range / Performance
Mini DTC P1126 - Throttle Position Sensor A and B Range / Performance Large Error

If those are the specific fault codes you're getting (not from a generic OBDII scanner) then you'll need to look at two things.
First, you do need to check the throttle body assembly and specifically the output voltage for the actuator.
The ECU is seeing values that are above or below expectations.

Second, make sure the throttle pedal assembly is sending the right signal to the ECU.
Verify that you're seeing proper voltage telling the ECU "how much" to open the throttle.

some PCM's need to be recalibrated after replacing the TPS or messing with anything like that. your AC should not "Bog" the car you should notice a ...slight... performance decrease and as far as hot ya it's going to do that. as long as your needle isn't above the half mark it's fine. I live in Phoenix... I know hot buddy it's already been 100 out this year.
