    Throttle Body Clean --> gas pedal vibration

    Makes me wonder if just reattaching the intake did it and nothing to do with the throttle body. Very possible.

    Throttle Body Clean --> gas pedal vibration

    Success! - vibration is 90% gone. Finally had some time to work on the Tahoe this past weekend. I removed the intake and unbolted the throttle body again, and checked around for any loose connections around the engine and found nothing. I'm pretty sure I overtightened the TB bolts originally...

    oil catch can

    I have a '13 Tahoe with 75000 miles with a new catch can installed. After a a couple thousand miles I drained about 2 tablespoons of muck, water and oil mix. Not sure what damage it would be doing, but it felt good not having that circulating through the engine. I think it's due to all these...

    Throttle Body Clean --> gas pedal vibration

    Thanks for the insights. There is vibration in reverse, but also in park (but less) and even in the brake pedal. It's most pronounced when AFM kicks in on the freeway, still only at certain RPM. Maybe time to have someone look at mounts. I considered a potential vacuum leak with the catch can...

    Throttle Body Clean --> gas pedal vibration

    A valid point, but the vibration began immediately after the TB clean. Might just be coincidence but it seems related. I'll check reverse and see if that points to a motor mount instead. It seems like it's dying away slowly, but might be that I'm just getting used to it. The first time I did...

    Throttle Body Clean --> gas pedal vibration

    Thanks. I'd considered that. The vibration has decreased over time, but is still there. It may be part of the relearn process, but after a month is still there. Gas mileage doesn't seem to be affected. I may try a full relearn and report back whether that shows any improvement.

    AOS/catch can

    I went with the one from catchcans.com. Install was simple, took maybe 15 minutes.

    Throttle Body Clean --> gas pedal vibration

    Quick update after spending a little time with the truck this weekend. The vibration is strongest at 700 and 1200 rpm, a little weaker in between 700 and 1200, and non-existent above 1200 rpm. I was wrong about park. It's just as strong in park and in motion, cruising or accelerating. You can...

    Throttle Body Clean --> gas pedal vibration

    I've got a 2013 Tahoe and decided to clean the throttle body last weekend. I took the TB fully off for a full clean and reinstalled. Plenty of gunk to clean out. Everything seemed to go smoothly including a quick clean of the MAF. The idle seems to be fine, no issues with performance. But...
