I have A 00 f150. It runs fine in park and reverse, put when put in drive boom stalls. I have already cleaned iac and replaced tcc. Put on code reader and 2 codes cOme up. P1747 and p0743. Any advice?

 

Well yes.
Both codes, if you are accurate, are transmission fault codes.
They are not engine codes so working on the engine won't solve anything.
You need to take it to a transmission shop for repairs.
The 743 code is trans torque converter clutch failure. Likely locked on causing the engine to stall.
The 1747 is the electric pressure control solenoid (EPC) is short circuited.
With faults like this it will stall the motor by the load it presents to the motor.

And-and put my check in the mail please!.
Good luck.
