Problem at Idle when in gear

1 1/2 years.. has 63k miles

 

Vacuum leak now?

 

Yea. I thought about that also..I will look at it today when I take the plugs out.

 

Start the truck and let it idle if it will and give little squirts of carb cleaner around your vacuum line connections and where your intake manifold seals up. Anywhere that makes the idle surge is your leak.

 

Ok.. so I went and bought some denso platnum plugs, switched them out and its runnin fine. I guess my truck didn't like the iridium plugs the shop put in. Hope I can get my money back for the 8$/each plugs.

 

I shift into neutral at a stop. Smooths out the vibs and as a benefit saves some fuel not fighting the Torque Converter
