Check the A/C Cluch . This is a common problem on today's Cars . If that is not it , It is most likely your Idler pulley for the Serpentine Belt , once they get some miles on them or a little dirt they start to be trouble . Hope this helps!!! Grant

I would start by replacing the battery in the key fob remote that goes on your keychain. You can take it to most auto part stores and they will test/replace the battery in the device. It's a fairly cheap fix. If the device still isn't working after a new battery, then you will need to replace the fob. Some auto part stores like, AutoZone, will carry some of them but some you need to go to your local GMC dealer.

The gas pedal could beva drive by wire, meaning there is no physical connection between it and the engine. You did not say the year of your Envoy. If it is there may be a bad accelerator position sensor. If is not drive by wire you may have an issue with your engine. Either way have it checked by a technician that knows you make of vehicle.

Transmissions that are overfull can "whip" the fluid, buy catching the fluid on the rotating parts. This is bad for a number of reasons,, It causes air to be trapped in the fluid (foam) causing a loss of the ability to transmit pressure to the apply devices, they hold the clutch packs and bands, and move pressure control valves, causing a slipping condition. this in turn causes damage to componets and a great deal of heat, also very bad for the transmission.

On the 2006 model, if you have the steering wheel with the on wheel buttons, keep pressing the i button on the bottom right until you reach Display Units: If it says Metric, press the carriage return button to switch it to English and there is the solution.

probably the fuel pump . could also be the coil . no idea the yr what it was doing any problems the day before ???

There are two O2 sensors, one on the exhaust manifold on the right side (passenger side) of the engine, and one just after the catalytic converter.

Problem could be a bad oil pressure sensor or the oil pump is failing. A mechanical oil pressure gauge needs to be hooked up to verify actual oil pressure. Problem could also be a bad stepper motor in the instrument cluster that drives the gauge.

Check fuel filter, air filter, sparkplug wires.

it sound like the oil pressure sending unit is bad Had a 91 chevy do the same thing

If mileage is over 100K and plugs have not been changed, it is time. Could also be a bad coil pack or vacuum leak at intake manifold.

It take quite a bit of effort to release the shaft. Try harder.

It is definitely an air leak, could be the hoses or the bags. Needs to be troubleshot.

Can you see the smoke colored sensor near the windshield? I've had one break and fall down which caused this exact problem. If you can see it, pull the plastic trim piece off, make sure the connections are actually connected, have seen these come unhooked.
