My truck has been back firing when I rev the engine after I start it no other time. Does anybody have any idea?

 

I think all these trucks do that, I know mine does.

 

Is it stock?

 

Yeah it's stock

 

Sounds odd for stock. Mine does it, but I have a free flowing exhaust. Is the motor cold when it happens?

 

Yes

 

don't rev a cold engine.....

what part of texas are you from btw?

 

agreed!

Pat, u still having that get together?

 

I'm from south Texas the coldest it gets is in the 60's. I have only reved the engine only a couple of times after I have already been driving the truck. The engine never completely cold. I have been told it might be an ingector.

 

yea give me a call saturday


I personally wouldnt rev an engine until it at a bare minimum starts reading off the bottom of the coolant temp gauge, and if possible wait until its up into the normal range.

 

I mean injector... I'm on my iPhone and sometimes it has a mind of it's own when it comes to spelling words

 

mine doesn't back fire. I'm not bone stock: CAI and tune

 

I heard that these trucks do that until they reach their operating temp since the computer is letting it run a little rich to warm it up, but I may be wrong, just something I read

 

Don't rev it................problem fixed.
