code 7 is for the TPS - probably why you have problem with throttle - was this a DPFI car converted to MPFI? - if so, were the wires switched on the TPS connector?
code 10 for Intake Air Temp and code 14 for Electronic Air Control Valve - usually when these codes show up together it means that the connectors are swapped - the IAT connector has 2-wires, one red with white stripe and one green with white stripe - the EACV connector also has 2 wires, one blue with yellow stripe and one black with yellow stripe - if the car was originally DPFI, the EACV connector is green in color - the IAT connector is white
