How to make my car misfire

Hey everyone, the last couple of weeks I've been having rough cold starts and multiple cylinder misfires. I believe it's my injectors because it only happens on cold starts and not at wot and there is always a slight fuel smell at start up.
The good news: my car, being a 2010, has the 10yr/120k mile warranty on the injectors . I've made an appointment at the dealership and they said they'd be happy to honor the warranty- if the injectors are causing the issues.

Bad news: the last two days the car has not triggered an ses light at cold start. The cold start is still rough but it doesn't seem to be misfiring as violently. Im afraid they'll say the car looks good and not replace my injectors.

So my predicament is I need to make my car start throwing codes. Anyone have any ideas?? Haha

you can cause a misfire by simply unplugging a ignition coil, or an injector. Problem with that is, they'll end up changing whatever you undid, and not solve the actual problem. Why don't you let them scan the ecu, see if there are stored codes, and try to actually fix the car?

Agree with the statement above, I wouldn't do anything to intentionally cause a mis-fire. Let them scan for codes, I'm sure there will be some history stored.
