Have you had anyone look at the vehicle since the concern started? Did you have any shifting concerns before going to the car wash? Thank you,

#28 of 46 gas cap leak repair
Mar 23, 2011 (8:05 am)
The check engine light and fuel cap light was always on in my 2004 Chevy Colorado. I was tired of spending the money on gas caps, and no one could figure out the problem in Michigan.
I recently moved to Texas where they have the emissions test. The truck failed due to a leak in the ***** evaporative emission control system*****
The repair facility had to smoke the system to find the leak. They replaced the evap cannister ($200 for part??) and everything is working fine at the moment, no fuel cap or check engine light.
now just set back and wait for the next repair

Very interesting... I just acquired a 2004 Colorado with the I-5 motor. It too is throwing the "Check fuel cap" code. Sometimes it will throw on the check engine light, and then switch over to the "check fuel cap" code. It usually only happens if I let the truck idle for a few minutes before driving off.
It will go away if I shut the truck off and then restart it. But now I am curious as to what this is? It sounds like it really isnt the fuel cap, but something else. It hasnt affected drive-ability yet, but I don't really want it too either. I also don't have a ton of money to throw at it. So if I can do something on my own without spending tons of money on parts that is what I am looking for.

#31 of 46 Fuel cap, tank overflow
Apr 01, 2011 (6:26 am)
I purchased an '04 Colorado last August. It has overflowed at the pump every time I've not manually shut off. Anyhow, I found this discussion, decided to call Chevrolet and found out that there is an extended coverage on the gas cap- even to secondary owners with expired warranties. Call Chevy at 1-800-630-2438. They will get you in to your local dealership for a look. Hope this helps some of you.

#34 of 46 06 GMC Canyon 4x4 fuel consumption
Nov 18, 2011 (12:00 pm)
I've had this vehicle for a year now. Its got about 70K on it and it hasnt been beaten. The problem im having is that I'm not getting the MPG's that its suppose to do, not even close its supposed to do 16 MPG for city driving and 21 MPG for hwy driving. I'm averaging in the summer around 13 MPG and less in the winter. All the things that I could do to help my fuel consumtion I did. Like add a new air filter, did a purge, flushed my oil a couple of times. I dont have big tires, I always try to keep my engine from reving over 2000 RPM. Is this normal? If not what is the solution? Thanks, Alex

The best fuel economy possible is the direct result of proper maintenance and good driving habits. Listed below are GM's recommendations to achieve the best mileage possible. The first group are things to consider for your vehicle, while the second are tips relating to your driving habits.
One of the major contributors to poor fuel economy are under inflated tires. Tires low with pressure create drag that the vehicle’s powertrain must overcome, wasting dollars in fuel. Always keep your tires inflated to the proper pressure as shown on the vehicle placard. This not only serves to increase gas mileage but cuts down on tire wear, further decreasing your costs per mile.
A vehicle that has a dirty air filter can’t efficiently draw air into the engine. This restriction forces the engine to expend energy to "breathe" wasting fuel in the process. Change recommendations are found in your vehicle Owner’s Manual.
Always use the proper viscosity oil in your engine. Oil that has a higher than required viscosity will create more drag on the internal components of the engine causing more work for it, especially when cold. Each Owner’s Manual contains information on the proper type of oil for your vehicle. Look for the "starburst" symbol on the front of the bottle, and the SM rating on the API circle on the back label. If you are in doubt, stop by your dealer for an oil change, and any other services required. Most current GM vehicles are equipped with oil life monitors to further assist on the "when" to change your oil. (Aveo/Wave/Optra/Epica currently do not have oil life monitors).
Note: GM Vehicles DO NOT require additional engine oil additives. Some additives may cause harmful effects to the internal seals and additionally void the terms of your vehicles New Car Warranty.
Purchasing higher than required octane fuel is a waste of money. Using higher octane fuels in a vehicle that only required regular unleaded fuel will neither increase performance nor improve gas mileage. In all cases refer to your owner’s manual and ONLY use the octane rated fuel recommended for your vehicle.
Even though current GM vehicles have 100,000 mi (160,000 km) service intervals for spark plugs if your vehicle is at that point in its life, have the spark plugs changed to assure proper running and continued efficient, trouble free operation.
Avoid quick/full throttle acceleration from a standstill in town and high cruising speeds on the interstates. While the optimum MPG for highway cruising speed varies from vehicle to vehicle, faster is almost always worse. If your vehicle is equipped with a Driver Information Center that displays Instant Fuel Economy, select that readout and vary your cruising speed while on the highway. The display will change continuously with uphill and downhill sections but you should quickly be able to identify on level ground the speed range that your vehicle does the best in. Avoid leaving unnecessary items in your trunk. It takes power to move increased weight and that means more gasoline consumption and reduced performance. While the change may be slight, multiplied by thousands of miles, it all adds up. Your vehicle uses much more fuel when the engine is cold. This is especially true in the winter months when the engine will take the longest to warm up. Combine errands or trips so that the vehicle only needs to warm up once to encompass many different stops.
If you still believe you have a concern please visit a dealer. They will be able to look into the situation.
