Many GM vehicle have this. It is to get the throttle body “warmer”, to keep it from icing, but warmer air coming in then mixing with fuel at the port also atomizes better which in turn helps the engine run smoother (when cold), and potentially help get it into closed loop operation sooner (along with any secondary…

Same issue on the Intrepids and other FWD LH cars. Not only was it the piss-poor placement for servicing, but even shielding it with the wheel well liner wasn’t enough to keep splashed out moisture out, which caused a shit ton of corrosion.

Oh gawd, I go off the wall seeing this.

GM “X” motors. For those that may not know, they were the 4 cam, 24 valve V6’s GM used from the early-90’s through the mid-90’s on W-Bodies, as the performance upgrade to somewhat compete with the Taurus SHO’s of the day. It was based on GM’s infamous 60* V6, which overall wasn’t a bad engine, but like anything else…

Not sure why you’re having such issues, never had any on ours. Should take about 5 minutes longer than the front 3.

And who exactly are you to determine what/how it is a problem for others?

When anyone complains about 80’s GM cars, I can buy the quality point to some degrees (I’m a former technician and have worked on everything under the sun, so I’m pretty well versed on things). But when they complain about wheezer 2.8L V6’s (and later the 3.1 V6), you have to take a step back into the 80’s and put…

Some of these are just being a car person though...

I look back at mine all the time when I park it here at work... Part of it is to admire it’s great looks, but the other part is to also see if some dooshhammer insisted on parking their $350 pile of crap next to it! This despite the fact that I park mine on the upper most yet still inside level of our garage, in the…

It isn’t any prettier here a few miles west of you in Chicago. I joke that for every inch of snow, they put down 2” of salt.

I know in this case these vehicles were road tested by an independent source, so some of the items, as well as those listed in comments would also have to be factored in, but for local EPA testing, it’s all done via a PCM scan. Dyno testing (IM240 roller testing), has long been abolished here due to liability issues…

Since the GMT900 platform came out (2007), the 6L80E/6L90E have been used. For the new K2Y’s, the 6L80E is the base transmission and the optional is the 8L90E on Tahoe’s/Suburban’s/Yukon’s/Escalades.

I read this comment about the Escalade sharing it’s powertrain with a Tahoe and immediately thought... “What the hell is wrong with this?” The Chevy/GM Small Block V8 is a time proven, STRONG performing engine.
