My CEL was on P0174 and P0171 codes.... Looked under the hood with a bright light and sure enough....there was a hole in boot. Used this guide to help with replacing it. Took about 2 hours. I've found that to work on anything in this car you pretty much need to pull everything around the area your working on out.. no exception here.

Have to say the CEL did go out immediately but it took almost a week and a half for the system to give a green light on the OBDII code reader. It can take a while for the OBD II to report a state of readiness. For anyone trying to get this to pass emmissions.......be patient, it's not the car it's the logic required by OBDII... It needs to make sure the fix is permanent.

Good write up....thanks.
