Sudden rough idle
 

Hey guys,

Like the title says, I have a 04 LQ4 (stock cam) and it has a new found chop at idle. It is like it can't make up it's mind if it wants to be cammed or stock. It only does it at idle and has not seemed to have lost any power. Any suggestions as to what it may be?


Thanks

Sounds like an intermittent miss...tons of things could be causing that.

It does not seem to be a big deal it does not die, and it does not do it when you roll into it.

The truck is creeping up on 138,000 miles could it be something is going out with age?

Ok this is now getting interesting the truck just threw a code. I'm not sure what it is I will have to pull it when I get home.
