Quick question....if an injector that was replaced

nopressurefuelpump · 06-27-2015, 02:55 AM

Wasn't coded, is there any codes or any way to tell of the guy didn't code that injector? New mechanic worked on my car, and just curious because of the engine bucking at wot at 110 mph. That's the only time it does it, and it just stops as soon as I let off the throttle.

If it wasn't coded in, then the flow rate on that injector would probably be wrong. Thus you'd end up with an overly-lean or overly-rich condition on that cylinder.
If it was bad enough, it would throw misfire codes (after consistent and heavy misfiring). Or maybe lean/rich codes.

I'd imagine that's one of my issues. I appreciate the help man.
