How is no one talking about all those packs of Marlboro reds 😂😂

[@HAYD101]

Did you catch the TP position before and after or the MAF reading? I got 2-4% TP position and MAF @ 3-5 g/s.... way to low but no vacuum leaks??

I found oil on the pcv hose is that good ?

Why waste money on throttke body if its working?

[@gregoryhearne9427]

Would this cats hard start and stutter at low rpms

[@BD-fq5rp]

Appreciate video but your explanation is incomplete. You said not to open butterfly with gas pedal all of the way down. But that’s what you did. If you’re not resetting position sensors, what should people do if they want to clean as you are doing? Peace.

You say don’t do it with the pedal all the way down because you’ll mess up the motor. But you’re doing it with the pedal down…. I’m confused

[@curtisseime8881]

His has a new Throttle position sensor that hasn’t been connected to the truck yet, plus the truck is off so having the pedal down won’t be trying to effect the throttle body

[@randitex25]

If I disconnect the battery would I still need to reset the throttle position?
