Hey everyone,

My car was throwing a P050A code which led to a CEL, flashing cruise and the traction control light. This code is associated with the cold start idle. After cleaning the throttle body out and cleared the code the engine began to run much smoother. I also oddly saw an improvement in gas mileage. I bought the car used over the summer and I am not completely sure how the build occurred. If anyone else is having this issue try to clean this! All you have to do is remove the top mount intercooler and piping around the throttle body. :)
