I'll be replacing the throttle body in my 2004 Ford Ranger (engine v6 3.0L vin-U, mileage ~ 130000) as the result of my previous post (see here Is hot desert weather the source of my recurring car problem?)
I was quoted $900 for the total cost. MSRP is $450 for this part, but I found it online for $280. Therefore I'm doin it myself.
I scoured youtube for instructions on TB replacement. I found information on the procedure for cars in general, and only one video specific to rangers.
My question is, are there any precautions or steps that mechanics take when replacing the throttle body? I'll also be replacing the idle air control at the same time since this was related to the original engine code (p0506), as discussed in the post linked above.
I noticed some folks wear latex gloves in these videos - is this just to keep stuff off their hands? Or is it because you have to be extra careful about letting any dust or residue into the system during the replacement?
