hi guys my eml came on yesterday and went off again but its idling very rough ,so i got the car on a computer and the codes i got up were

P1120-THROTTLE CONTROL VALVE (BROKEN TUBE)
P0170 FUEL TRIM MALFUNCTION (BANK 1)

now i reckon fuel trim could be a lambda sensor ??
but after searching online i still not sure for throttle control valve could it be throttle position sensor??? i cant aford much to spend just now so if any might know if it could be that ? or somthing else ?let me know .
cheers
