Question about 2006 GMC Envoy

2006 5.3 liter GMC Envoy

Howdy milespeed, I want to thank you for the great ideas of other possible sources of the problem. The one thing that I really need to know is where is the mass air sensor located; I do not want to pull the wrong one and create a new problem.

Where are the oxygen sensors located on a 2006 gmc envoy

We have 2 locations, upstream before the CAT, and dowstream below the CAT. The upstream is on the passenger side at the exaust manifold very easy to access from the top. The downstream one is after the cat, accessible from underneath. The connector for this one is a PIA, up near the top of the tranny. But doable if you're in the right position.

My 2006 gmc envoy is having problems with the four wheel drive...when its in 4wd and I turn right or left..its like the brakes are locking up or something is preventing my truck from moving....does anyone...

never use 4wd on dry pavement even just wet pavement can cause this. 4wd is for only snowy or slippery conditions

unless this is automatic 4wd or awd than u have a problem id suggest you find a forum for youre vehicle and post it there find one by googleing gmc envoy forums or chevy trailblazer forums as they are the same thing

Noise in intake manifold 2006 envoy

A few generic ideas come to mind:

loose/worn choke plate hinges
worn/sticking choke plate seat
sticking throttle linkage in need of lubrication
leaking intake hose - causing hissing as air gets sucked in through the leak
loose intake manifold body - check tightness of bolts

For more specific ideas:
In 2006 GMC manufactured the Envoy in both 2WD and 4WD versions:
with available engines:
6 Cylinders S 4.2L SFI DOHC
8 Cylinders M 5.3L SFI OHV

What type of fuel recomended for 2006 gmc envoy

Fortunately the way they refine fuel these days and the way they engineer these cars and engines, the lowest grade is sufficient and will not cause any damage to the engine or void any warranties. So in short, 87 octane is just fine.
