Check Engine Light? 2006 GMC Canyon?

means too much air on bank 1. Wrong air/fuel mixture. So this is usually a faulty sensor so into the garage for a diagnosis of which one is a problem. The error will cause you to use more fuel as too lean means not rich enough so more fuel being injected to compensate.

Could be fuel supply problem as well.

I have a 2006 GMC Canyon 84000 miles and the engine will start but dies after a few minutes then says low power, have to wait a few more minutes to start it again.Any one have any suggestions,That I think would be a vacume hose or is it something else.Sorry no code yet as I havnt taken it to anybody .

2006 Gmc Canyon Problems

Lean is too much air look for vacuum leaks

Most likely faulty sensor

o2 sensor is reading wrong it should be under warranty yet bring in emissions are covered to 70 thousand miles

Here is what I would look for bad or dirty p.c.v .valve Positive crank case ventilation. or bad or loose gas cap.. on my 01 GMC is what I found after buying 400.00 worth of 02 sensors.

I own a shop, and what I think is this; Bank #1 means there is a problem on that side of the engine. It means something is wrong; such as a sticking injector allowing too much fuel into the engine, a bad spark plug not burning all the fuel, or even a leaking intake gasket on that bank. The most common cause is; an injector that is not closing off all the way due to build up, which allows it to keep putting fuel into the cylinder even after its supposed to be closed off. A vacuum hose that is split where it plugs on, it came off, cracked & leaking, or collapsing for whatever reason. Remove the spark plugs on that bank, and compare the way the electrodes look. Usually the cylinder that is the culprit will be wet looking, or will look different from the rest of the plugs. Listen to the injectors as they fire, and you should be able to hear one that is different sounding. You can use a piece of pipe to listen to them with. A lazy injector can do this, and sometimes you have to replace it with a new or rebuilt injector to resolve the problem. On the cylinder that looks different, you will want to make sure its not a firing problem such as a weak coil before you replace the injector.

Glad to help out, Good Luck!!!

Sounds like a clogged fuel injector maybe.

It could be as simple as a vacuum leak but remember if the truck is under 36,000 miles it is still under warranty.

you fuel mixture is off, could be an injector problem. go see a mechanic
