my 2004 lexus gs300 has been throwing trouble codes for a variety of different things ive been dialing them in one by one and got it ready for smog and on the way to the shop for smog it throws its self into limp mode, and throws trouble codes P2111,P2119, and C1201 i took it to a shop and they were unable to completely remedy it as i cleared the code, so the shop cleans the throttle body and told me if the problem comes back up i need a new throttle body, i previously replaced the TPS and O2 sensors and the lights stayed gone for about a month until i went for my smog and perfect timing codes came right back. I know the thread is kinda confusing but so is the situation so bear with me.
