Always start diagnostics/repairs with the lowest numbered Check Engine Light (CEL) trouble code. Often whatever is faulty and causing the lowest number code, is also causing bad data or some other engine issues that make the higher number codes illuminate the CEL.
A P0138 can cause all sorts of issues, including a very rich mixture, cat converter troubles, and bucking, stalling, or backfiring of the engine.
Fix the P0138, erase the codes, and see if any other codes come back.
