Maintenance to do after picking up your "new" truck

[adventurenali92]

If you remove it from the truck your good, if you clean it on the truck and open the throttle blade up you can throw the calibration off and you’ll have to do an idle relearn, and it’s best to remove it anyways so you get all the crap on the backside out

I’m guessing taking it off the truck is the tricky bit?!

I think it’s 3 nuts you have to remove, and you can either put some rags under it and clean it there or disconnect the coolant hose that goes through it and clean it off the truck, I’d replace the throttle body gasket too it’s under $10 for a Felpro one

I've cleaned several on 00. 03. 04, 12 on the truck and never had anything happen than have it sputter once or twice at initial startup from the spray fumes being in the intake system, I have replaced the IAC also and within a minute it was back to normal idle, on my 12 I even completely swapped mine out for the ls7 throttle body and it was plug n play. only vehicle I ever had to have relearned was as a stupid nissan maxima.

id avoid a trans flush if the fluid is not red still.

if its brown and smells burnt, a flush could kill the tranny on the spot. pan drop is much safer leaving a lot of the old fluid. the old fluid is all thats making it move, flush it and it could die.

why it took me 6 months to find the one i got, they all had brown tranny fluid. and i was not into a trans job off the bat when they would not drop the price.

Fixed that

Clean the mass air flow sensor and the throttle body.

Added that in

When I got my tahoe I cleaned the throttle body and injectors and injectors ports. I removed the injectors and used B12 and q-tips they were all gummed up and the injectors had a film from gunk and gas cooked on to the face. After cleaning those I got about 3-4 extra mpg and it was an easy job. YouTube is amazing

I'll be doing this to my yukon when it warms up

Stuff works really well and after you use it to clean the ports and injector faces you can put it in the tank. I just bought a can of it at autozone or advance auto

I poured a little into a container and soaked the ends of the injectors while I cleaned the ports
