2022 2trfe Backfire Randomly??

Does anyone know why my practically new (20k miles) Tacoma would be backfiring sometimes on startup? It’s like every once in a while and totally is random could happen twice a day, or could go without it backfiring for months. Did I get a lemon? Maintence is always a priority for me i’ve never missed a thing. Any help?

 

Properly gap your points

 

?

 

What?????

You mean the plugs?

Even then, It ain't likely to be the plugs.

 

OP, does the the backfire sound like it's coming from the exhaust or intake (hood area)?

 

Are you sure it's a backfire and not a misfire?

It's very rare to see a modern fuel injected engine backfire.

 

Have you checked for codes? That should point you in a good direction

 

My 2021 has made a small popping sound from somewhere in the exhaust under the truck since I have had it. It only happens on startup and not all the time. Very rarely (maybe once a month). Truck runs flawlessly and no lights. I have 35K on the odometer btw

 

No it’s coming from the exhaust for sure. Idrk what a miss fire is haha

 

I think it is something to do with the air pump that comes on when you first crank it up. The older 2trfe trucks had this issue also. I dont think it hurts anything though.

 

A misfire is when a cylinder doesn't fire properly or at all.
This is what a misfire typically sounds like in the exhaust.
