If the SES light goes out after a couple days, is it worth worrying about? It still lights briefly at startup.
Also, do the people at Advanced Auto generally know how to check codes? Or am I likely to have a totally unqualified person playing with the ECM?
Thanks!
Personally it would drive me crazy not knowing what the code was. :) Go ahead and have them read it, it'll be stored in memory even after the light goes off, won't hurt the car - and write down the code and post it.
The light is supposed to come on when starting the car up as do the other lights like ABS-airbag,etc.They are performing self checks-anyway checking the codes does not allow any inputs back into the computer-it can't screw anything up.
The code set was P1416 - Auxiliary emission Controls. The guy at Advanced Auto said he got htis once and it was his gas cap. My light went out the day after a I got another tank of gas so maybe this was it.
Overall the car runs fine except it's runs a little rough when first started until it gets warm.
I'm thinking it might need new plugs since I have 75K and 8 years on the originals.
Any other ideas?
Thanks!
Yes, after that long, it's time for new plugs and wires.
New plugs wouldn't hurt - but P1416 is Secondary Air Injection (AIR) System Bank 2, probably not your gas cap, that's usually P0440.

SOmeone was saying a diverter valve my be bad. Anbody have a picture of what this might look like? I haven't a clue where it to find it.
I did notice my PCV line was unhooked from the PCV valve. I had been pulling on the foam padding trying to figure out if that was the PCV Valve a few days before I got the SES light. Last night I went to put a new PCV in and noticed it was unhooked. It runs much smoother now when it's cold.
