Hello, I'm Cam. Please include all the details about your issue so I can accurately advise you. I cannot see your vehicle so please be detailed.
Do you know what code set?
No. I don't have a code reader
Ok it could be a gas cap, other emissions issue, knock sensors, just about anything, can you get a code reader or get a part store to read the cods?
Yes, I can have a parts store read the codes. If not, I'll get a reader. I replaced the gas cap in March, but it did not help much. The light did not come on as often, so I continued to use the old cap. Doe this emissiion system have a 100,00o mile warranty?
No, they do not on these,
Get the code then return here to me with it and I can help you figure out if we need to deal with it and what the costs would be .
Can I get back to you tomorrow on this?

I got the codes read at O'Reily Auto Parts and the mgr said it was low voltage to all 4 oxygen sensors and also low voltage to the MAF sensor. I did not write down the codes, just the parts that were malfunctioning according to the codes.
I cleaned the MAF sensor with the proper cleaner, reconnected the battery, test drove the truck and the check engine light came on after a few minutes of driving.
I have not replaced any parts yet.
I cleaned the MAF filter with MAF spray cleaner, as previously noted. The check engine icon stayed off until the engine reached operating temp, then it cameon again. Should I replace the MAF sensor?
I installed a K&N air filter, July, 2010 to improve air flow through the engine because I pull a 4000 lb travel trailer over 12,000' Colorado mountain passes in the summer. The filter seems to give the engine a little more torque under these conditions. The filter has about 12,000 miles on it? Should I clean it or simply replace it with an disposable paper filter?
The exhaust seems to be clear of obstructions by visual inspection of the tail pipe.
