• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

Please help!

My 2000 Grand prix GT 3.8L 166k miles has been stalling and rpms fluctuate when warm. (can make it not stall by hitting gas pedal).
I have put a new fuel pump, spark plugs, MAP and wires. I got 3 codes, P0122 - P0650 - P1122.
Can somebody please help me? Maybe someone has had a similar problem? Side note: Has been to the same mechanic 3 times now he can not figure it out... getting irritated! would love to start driving it again!
 


ill list the codes below:
P0122-- Throttle Position Sensor/Switch A Circuit Low Input

P0650-- Malfunction Indicator Lamp (MIL) Control Circuit)
P1122--Throttle Position Sensor Circuit Intermittent Low Voltage

Also, my service engine light is not on.. never has been.. wonder if the bulb is burnt out?
 
As well there's something wrong with the SES light. that's code 650. I'd start by checking the bulb. Obviously after you check the TPS and it's wiring.
