Check Engine Light

I recently had my check engine light go on. I have an 04 4wd canyon w/ z71 pkg, 5-cyl. I took it in to autozone to check the codes and a code corresponding to a bad o2 sensor came up. I changed the gas filter (removed the neg cable) and the ck engine light went away (i have 30 k on it). However later about 200 miles later the ck engine light came on again and then went away. I have not seen the engine light come back for about 100 miles.
Any thoughts if this is the initial signs of the bad cylinder head problem i have seen on this discussion board. Thanks.

Thanks for you responce, I was thought the same thing. I have been making sure to change my oil regularily. I guess i will look into taking care of the chain tentioner. Then we'll see if there is a difference.

That is a sign of a poor dealer service center. If a mechanic/service manager can't diagnose a problem without codes than they are not very good at what they do. Check with another dealership.

i had the same problem with my colorado. About the tensioner.The service center said it takes a second to pump up the racket system on the tensioner.Well that sounds like a premature wear problem. My truck sounds like a deisel starting up.They told me to stop using any other filter except delco.I tried it and it didnt change the noise at start up.Heres another problem. Has anyone noticed and abnormal wear on the inside of there front tires.The factory set them in so they will not rub the inner wheel well. The dealership should of changed this if they did the new car prep right.My front tires are at the wear bars at 12,000 miles.So spread the news maybe GM might be listening.They wont listen to my truck problems.

"dbcrue", yes, valve seats became hardened at that point in time. However, many engines today, including those in the Canyon, have aluminum cylinder heads. That in itself, would require valve seat inserts of some kind, as aluminum is way too soft to act as a valve seat.
In fact, my first car, a 1965 Chevy Corvair, had an aluminum engine, and valve seat inserts in the heads.

"cruznt2", are your tires wearing evenly across the tread? If not, then you should have the front end alignment performed on the truck, before throwing more tires at it. If they are wearing evenly, and simply wearing out, I suggest you buy better tires.
If it's any consolation, when I bought my '05 Canyon 4x4, it came with the 265/75/15 General Ameritech tires. Poorest excuse for a tire I've ever driven on. They were off the truck within a week (3-400 miles), and I say this in all honesty, I GAVE THEM AWAY!!

I have the 08 Chevy Colorado w/the 2.9L engine. Experiencing the same problems with engine knock during a cold start. Service managers and GM customer serv reps are all giving me the run around. What type of engine do you have in your new Canyon? I am also experiencing severe leaks inside the cab. Testing w/a hose on my own, I can tell the water is coming in from the back somewhere. GM and the service manager at Chevy tried to tell me the water was entering the car through a vent. Actually told me I have to keep my vent on recirculate when there is wet weather. What a joke! With all these issues occuring within the 1st year of ownership, GM wants to tear the truck apart, but not give me a new truck. Did you pursue the Lemon Law at all while dealing w/all of your issues? If anyone is having similiar issues, please let me know and contact GM or your service department, because it is definitely an issue.
