- 2005 Ford Explorer
Bought a 2005 Ford Explorer with 117000 six months ago. Passed CO emissions test, drove well, etc.
Moved to CA last semester for graduate school, didn't transfer title over (used the student card for a while).
This summer I spent in Florida, car sat for 2-3 months. Had my landlord run it once, no issues.
Came back a few days ago to a 100% dead car. A jump later and the car is alive, really didn't want to turn over, wouldn't hold an idle, CEL blinking, etc..
After running it for 30 minutes it could hold it's own idle and the battery was able to start the engine. Should mention that the exhaust wasn't colored but it was rather gas-smelly to me.
Still having the sometimes solid, sometimes blinking CEL.
Took it to Autozone, they read two codes. Once about a misfire and one about low coolant level, guy told me my coolant looked fine (like it was at level) and that the issue was probably just the computer needing to something or other, come back if it persists after having driven it 80 miles.
So I went to get my CA emissions check, didn't go well. That guy read several codes.
P0172 - System Too Rich Bank 1
P0174 - System Too Lean Bank 2
P0300 - Random Multiple Cylinder Misfire Detected
P0301 - Cylinder 1 Misfire
P0302 - Cylinder 2 Misfire
P0303 - Cylinder 3 Misfire
and
P0316 - Engine Misfire Detected on Startup (First 1000 rev)
Given that the car ran fine with no CEL two months ago, and ran fine when the landlord ran it (before the battery died) about a month ago (no CEL) and that whatever has gone wrong is obviously only affecting half the cylinders, I'm wondering what the common denominator might be?
Maybe a stuck O2 sensor that specifically works on the passenger side bank or something? Any help would be appreciated.
I've read two similar threads:
Rich Bank 1 + Cylinders 1, 2, 3 misfires at startup
https://www.explorerforum.com/forum...301-p0302-p0303-p0172-and-p0174-codes.308822/
Both seem like timing belt / idler issues. I really hope this isn't the issue but I need an honest opinion. That's probably not something I can do on my own.
