so i have a 2006 acura tl with 178,000 miles on it. as of recently my check engine light came on. i went into autozone and it came back as my o2 senors. i then went to my mechanic and they said my o2 do not need to be replaced and that it issue could be underlying like my computer could be busted or there are dirty wires or a rotted wire. the car runs very smooth but the engine light just keeps staying on even when they disconnected it from the battery. as of recently when my car is just sitting, its hard to start it. itll make the clicking noise before turning on and its run smooth the entire time. when i turn it off and back on a second or third time it would start perfectly fine. but when i first start the car, the vsa, abs and engine lights are on but when i turn it off and on again it the vsa and abs lights would turn off until I start it up the next day it'd do the same thing over again. I read somewhere it could be a battery, as mine is now 3 years old. I just want to know if anyone else has had this problem and what i should do.

There was an issue with the air conditioning vent tube clogging up and will make the pcm wet. What exactly was the code for the light being on? If you are not mechanically inclined then I would have the shop check that out first and yes have the battery checked also. If your battery is being drained over night or after a couple days it is probably due to the HFL unit. Try a couple searches on the site or google and these issues/solutions will pop up. Good luck

A few comments:

• Find a new mechanic.
• Replace the O2 sensors, use either Denso or NKT sensors.
• Yes, a 3-year old battery in a 3G TL is getting long in the tooth, I'd replace it as well.
