I just put a new motor in my talon and when the car heats up the car runs real lean and shuts down at any boost.. I pulled the plugs out after 4 days and they were white. If i start the car in the morning or after a couple of hours it will boost up fine but when it heats up the problem occurs. I put the car on the logger and it shows 9 counts of knock when the car shuts down like a bad ass fuel cut.. its like it stops getting spart and fuel. On the diagnostic check 02 sensor, throttle position sensor, and knock sensor showed up for errors.. I tried a different 02 and that really didnt help.. I've tried wires, fuel filters, but i just cant figure it out, anyone have this problem or suggestions please let me know..

thank for the space
 
Have you cleaned or replaced the TPS?

Don't drive it like this, if you haven't already gone through detonation, you will.
 
I havnt tried cleaning or replacing the tps yet , i was going to do that last out of the 3 things, tonight i did the knock sensor and that didnt help, my o2 sensor will be here today so i can try that and see if it works, if not then i will replace the tps... I already get detonation but it is only 3500 rpm and above in boost, if i drive it normally or when its still cold it will not act up..
