Please, I beg someone, help me.

I have a 2007 Chevy Tahoe that has been in and out of the shop 3 different times over the last week. The stabilitrack off light came on as well as reduced engine power light. They coded it out and originally thought it was the throttle sensor. Fixed it twice with new part each time.

I have read several different forums hoping I could take it to my mechanic with suggestions.

I do not have on star, which was a solution for some.

If anyone has had this same issue and can provide me with some insight it would be very much appreciated.

I hope I did this correctly.

Thanks to all who took the time to read.

What are/were the codes?

What was replaced?

Onstar will NEVER be of any use for this. All they can do is tell you what codes are in the system.

Gotta have the codes to get started.  What state or city do you live?  There might be someone from these forums with a scan tool that could help.

I live in Grayling ,Mi. I am not sure what the codes were. I know he said it threw two different ones. One being the Throttle position sensor and the other being the gas petal sensor that works with it. He replaced both the parts and it's still doing it. I disconnected the battery because I saw that it has worked for some to reset. Again, not a solution. II am at a loss.

I'll throw this out as a long shot....  Check your battery and cables.  If there is an issue in the electrical system, it can cause weird codes to be thrown.

Ok Going to try to help you without knowing the codes which is a mistake. It is kinda like the blind leading the blind.

 

If it is a throttle position code and they through a throttle body at it and it didn't fix it most likely it is in the wiring (there is a GM Bulletin on the TB connector being a problem)

 

Personally if it were my truck and I had a TP1 or TP2 code setting I would replace the connector with (6 pin 88988106 connector - http://amzn.to/2zZAMvg) and run new wires from the connector to the ECM (you will need micro 64 terminals - http://amzn.to/2jQDc9A ) (you will need a terminal crimping tool if you don't have one - http://amzn.to/2A2blt9)

 

These wires run straight from the TB to the ECM so you should be able to wiggle test the wires and get it to act up. A lot of times what I see is where the wires go into the connector itself there will be a little bend and the wire will be white. I see this a lot on the yellow (581) and purple (486) wire. If you give it a little tug the wire will separate and you know that's where the break is in the wire.

 

This is just my suggestion without knowing any of the codes. I do all the electrical work at the dealership I work at and have been for the last 17 years.

 

Here is a schematic in case you decide to go that route.

Get the codes read and have them tell you the actual codes.  

Something funny. I was listening to https://www.yout ube.com/watch?v=My5lL0_sURw When I pressed Play on your video in your signature and it kinda synced lol. I put a Space between yout ube so it wouldn't post a video on here lol.

      The Peckish Synapse

      By Grumpy Bear · Posted

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.
