I couldn't find out what type of engine I had F23A1 or F23A4, then I noticed on the black plastic belt cover on the driver's side of the engine next to the valve cover, there's a white label with F23A4 on it.
Thanks for the good info. I have code 1167 and all the fuses are good. I'm going to change the air filter and run some fuel injector cleaner through the gas tank, then if that doesn't help I'll buy the Honda part for a SULEV (currently $310.00 + tax) unless AutoZone can prove to me that their $119.00 Bosch version will work for a SULEV. I also noticed a Denso version which has the right Honda part no. for $189. on Amazon.com.
