: 2003 Escalade Stuttering

I'm trying to figure out why my 03 Escalade 6.0l is stuttering, I was backing out of garage and it was idling rough under 1000rpm and then tried to go in drive and it stuttered a bit.
I put it in neutral and revved it up a bit and after a couple tries it revved up. I drove away and every once in a while it stuttered hard.
Any ideas? Any suggestions would be great.

Thanks!

Did you get a "Reduced Engine Power Warning"?

No warnings at all have shown. I didn't drive it today for fear of damaging something but will drive it around town tonight.

Clean the throttle body before you drive it again and see if that makes a difference

Pulled the codes and PP171B & P0174B fuel system lean banks 1 and 2. I'm just guessing but possible intake gaskets?

Lean means fuel issues most likely in the fuel system and line

Intake air leaks. Spray around the intake with starting fluid while the engine is running to find hidden leaks. Be careful. Your hair and eyebrows will grow back out in a couple of weeks.

I laughed my head off when I read that but you are correct about the ops issue
