Question

Code reader states the codes po449, p1516, p1682, p2101.. whts the best way to fix all four at one time..

Answer 1

Just 2 codes are for the same problem (P1516, P2101 = Throttle Body), the other two are for something else. The first thing you need to do is clear all the codes, then try to fix the code that comes back first.
