So I just bought this Audi A6 off someone and he did let me know it had a p0068 code which I seen is maf/map sensor which I had no issue fixing now I'm still learning about my car and I did also just clean the throttle body yesterday the car was running fine then all the sudden today the ec light kept coming on and causing my car to go in limp mode anytime I stopped or was in low rpms once I got up to 50 to 60 mph the car was fine I been trying to find out after you clean the throttle body does it need a alignment and also I was getting manifold stuck codes but now they are gone ever since I cleaned the throttle body now I just keep getting limp mode and p0068 p2101 code what do I need to do to fix this and what needs to be cleaned or replaced. It does have rough idle the engine light turns on immediately I do have my own Bluetooth scanner that I can keep in the car so I can see what's going on with everything else also it also stutters to shift when slowing down and stopping I think I would need a map sensor replacement and tps and now tac fix if I'm correct if not please correct me.
