Fun With Purge Valves and CELs
Alright, so i've been battling a CEL for the past few weeks and i wanted to run the whole process past you guys and see what else i should do.
Originally it threw the CEL and returned a P1443 code, which is a purge valve failure of some sort... i forget the exact thing. Anyway, i googled the issue and most sources say its either a leak in the system or a bad purge valve/sensor. Starting with the cheapest option, i replaced all the rubber lines. No change. Changed the solenoid, same thing... no change. However the light was out for about 90 miles before i came back on. Next i replaced the sensor, and the light was out for one starting cycle. After reattaching the battery and driving, it returned when i started the truck again.
Sunday afternoon i was replacing my rear window in my garage and noticed the faint smell of gas lingering in the garage, so i know i stlll have a leak somewhere. Where should i go from here?
The truck is a '96 2.3L. About 178k on it. Im also getting about 17-18mpg through mixed city/highway driving, so maybe that is could be another clue as to whats causing my problem.
Oh gurus of all things Ranger...where should i go from here?
