I'm embarrassed to show my 1999 GS 300 because she still a work in progress. I've had her for about 3 years now, no problems till recently. She has over 215,000 miles and no mods as of yet, the only one mod is a K&N filter with the purple stuff running in her. That's pretty much it. The problems I'm having right now, and I do need some good suggestions on what to do, is... My throttle position sensor code p11123 not sure exactly the code because I don't have it in front of me but close to that number I just type. Please help me figure out exactly what I should do. I changed the throttle actuator or motor that controls the throttle flap, but not the TPS sensor, I feel it's the whole throttle body but I need to know if it's necessary to have replace the whole thing or throttle body. Please help.
