Suggestions on a POS chevy truck

[jtyler]

Anybody ever get a mesage in a chevy that says "Stabilitrak off, Service stabilitrak and then Engine power reduced and starts running like crap/ My 2010 started doing that. Shut it off for a couple minutes and it'd be gtg. Friday started happening every 10 miles or so and next day it wouldn't start. Cleaned the throttle body with throttle body cleaner and the MAF sensor with MAF cleaner. Anybody have any other ideas? I hate late model computer controlled vehicles!

You may have a wheel sensor out.

Holler at Dcav, he may have a better idea.

You might have triggered the Auto Suspension Adjust thing.....by possibly taking a turn too sharp, causes the suspension to drop & automatically
causes power to "almost" shut down until reset.

It's the TPS. this is a common issue on the 07+ Chevy's.

TPS? What do I do about that? It's got 170,000 miles on it. Does that matter?

You just stay away. You want to shoot everything

Check the codes. They are pretty good at telling you where to look. It isn't going to get better by cleaning anything.

All you can do is replace it as a unit. The whole throttle body will have to be replaced. I believe there was a service bulletin issued awhile back, so there's a chance the dealer may warranty it for you.

Not with 170,000 on it. Crap. Thanks for the help!

 

[alexrex20]

Even with that many miles, a recent TSB (technical service bulletin) would require them to replace the affected part at no cost to you. Worth looking into.

A 2010 with 170,000 miles......that's alot of driving, lol.

 

[jtyler]

I get around! Thanks for the tip. Looking into it now

lmao... so if you corner hard it causes a fault?

I don't know about a "fault", but a friends Suburban had a suspension package that was set up to drop the rear end in event of
an evasive type manuver to lower the center of gravity to help prevent rollover, it also caused the engine power to drop to
almost nothing.....I thought he could have the same set up.

The TPS is built into the t-body? That sucks.

 

[alexrex20]

Ya, it's drive-by-wire so the TPS is also the throttle plate actuator. Thankfully, they're a lot cheaper than the old cable-actuated throttle bodies. On this Chevy it should be about $100 for the whole thing.

Bhaaa, too much trouble.


Bring it to Hicksville.
