Where is the vacuum hose on a 2005 gmc envoy


There are several. They go to the transmission, the idle control valve, the fuel cannister, cruise control fuel pressure regulator and inside to the heater/ ac controls There is a place on the intake manifold where a vacuum hose will connect to that distributes vacuum to all the other places vacuum is needed.

Can someone please help me figur out what is wrong with my Envoy? running on 1 or 2 cylinders, irratic idle,light surge, doen't want to stay started, flat on the floor sitting still doesn't go


check the fuel pressure at the fuel rail. you will see a small black cap like you find on a tire. unscrew it and you should see a pin in the middle and the valve will look exactly like the valve on a tire where you put air in. take a small nail or key or something and gently push the pin down while the key is in the on postion.BE CAREFUL AS GAS WILL SHOOT OUT OF THE VALVE!! Make sure you listen close if air comes out with the gas.Keep holding pin down til all air is out and only gas is shooting out. this should solve your problem if not try again and if you have more air in fuel line then you have a leak in fuel line

I am having a problem with my 98 mazda protege, 1.8l car. When i put it in drive, it takes about 2 or 3 seconds most times to really accelerate and when i am at a stop, it idles irratically, fluctuating...


Check the wheels and see if the drums are not tight. and also the erratic Idling Could be from your Torque converter Clutch Solenoid that doesn't work properly and if the Solenoid gets totally bad then your car will be stalling.all Well i can say is Check your transmission fluid level and your brakes. Good luck
