My 88 Gt has been running really bad lately. When its fully warmed up it wants to usually when the rpms drop, like when i push in the clutch at a red light or coasting down hill. Its the worst when ive been driving the car and i make a stop where i have to shut the car off. when i start the car it will fire up right away but then die just as fast. It will keep doing this unless i rev it up a few times. I know that its running rich cause i can smell raw fuel and im getting crap for fuel mileage. I found 3 codes. Koeo 81, 82 and Koer 92. Does anyone know what these mean?
Need help with trouble codes

Code 81 – Secondary Air Injection Diverter Solenoid failure AM2. The secondary air diverter valve (rear vacuum operated valve) isn’t working on the Thermactor Air System (smog pump). Look for broken or missing vacuum lines on the solenoid valve to the diverter valve. The solenoid valve is located on the back side of the passenger side wheel well. Check the solenoid valve for +12 volts at the Red wire and look for the Lt Green/Black wire to switch from +12 volts to 1 volt or less. The computer controls the valve by providing a ground path on the LT Green/Black wire for the solenoid valve.

Code 82 – Secondary Air Injection Diverter Solenoid failure AM1. The dump valve air diverter valve (front vacuum operated valve) isn’t working on the Thermactor Air System (smog pump). Look for broken or missing vacuum lines on the solenoid valve to the diverter valve Check the solenoid valve for +12 volts at the Red wire and look for the Red/White wire to switch from +12 volts to 1 volt or less. The computer controls the valve by providing a ground path on the Red/White wire for the solenoid valve
Code 92 - Left HEGO (O2 sensor) indicates system rich. Look for a leaking fuel injector or fuel injector to computer wire shorted to ground on the LH side of the engine.
