2004 Chevrolet TrailBlazer EXT LS 4WD 4dr SUV (4.2L 6cyl 4A)
Had this from day one.
Just had dealer replace the exhaust manifold ($100 cost to me, could have beem $770).
Cracking of the manifold is common, rear of the O2 sensor.
If you smell exhaust under the hood when cold and freshly started, as well as a strange noise that clears up in 3-5 minutes, you have the problem.
GM covered this up to 8 years and 80K miles for free, I was lucky to get for $100.
Thanx GM :)
Replaced all four antisway links myself, easy (gets rid of clunking when going over bumps).
Also had to replace all four brake rotors and pad sets.
Very happy with the Rugged Trail T/As, 94K mi. on the remaining orig. pair.
Installed K&N cold air intake kit, no diff in econ.
Plenty of power with standard I6, 3.42 rear end, 4X4 to pull a 4,398# Wilderness trailer, and family of 5 with all our gear.
Can make up for lacking cargo capacity with hitch mounted carrier, and roof carrier.
With those 2, i match the cu. ft. of the Suburban.
Would like outside temperature and trip computer for mileage.
The voice recording feature is useless, really, what were they thinking?
Also, would be nice if seats were easier to remove (clip in vs. existing bolt in seating).
