Code 24 is the air temp sensor inside your afm.

The Code 51 is probably a poorly adjusted, or dirty, TPS

Here ya go:

Test/check the TPS:

Check the connection on the AFM, make sure it's good and secure. Still have the problem? Bench test it:

Could another code say Code 22 set off Code 24? The wires to the water temp sensor snapped so my dad is going to sauder them together tommorow. Also would these codes attribute to my car dieing everytime the throttle is opened, or would that be my timing. Right now since Me and Steven89 installed a working CPS into my car and set the timing to 10'. For a second question as I tried serching what's the correct timing for a Auto 7MGTE.
