Default 2005 c230k check engine light-running lean error code?

my check engine light came on about a month ago..i took it to autozone to test out the error, they said the error code came back as my car is running to lean. they said fuel injector cleaner may help..so i tried that, 2 days later the light went off..so it was fine for about amonth..that light has came back on and i got the same error code..what can it be? and what is the cost to correct this? thanks everyone!

Do you remember the code? I can look it up and see what it says in my book that came with my scanner. Or you can look it up on the Actron website.

thanks for responding! went back to autozone..its PO 128 ...which was coolant temperature below operating range--"fAULTY thermostat or faulty CTS"..so can i buy a thermostat at a parts store like BAP? and can i do this work on my own? the guy at auto zone stating its pretty simple to do..

Yes, Ihad the PO128 code some time ago and it turned out to be the thermostat. It's not a hard job and it's right up top in front of the engine. You will see it there. Get some of the correct antifreeze and a thermostat (I don't know about BAP or if they have it) but there are plenty of places online to get parts and replace it with a flush at the same time. These cars are known for this from what I can tell.

I like www.autohausaz.com
