I just bought a good condition 71k 97 Ford Ranger, but I can't even get it registered right now because it won't pass emissions in this state.
The P0155 code is stored and all the rest are pending-I just switched out the 02 sensor for the P0155 code (because that's what the previous owner told me the problem was), cleared the codes, but now they've all come back. I'm thinking it's got to be a vacuum leak, and possibly an electrical issue.
P0135 02 Sensor Heater Circuit Malfunction (Bank 1 Sensor 1)
P0141 02 Sensor Heater Circuit Malfunction (Bank 1 Sensor 2)
P0155 02 Sensor Heater Circuit Malfunction (Bank 2 Sensor 1)
P1131 - Lack of Upstream Heated Oxygen Sensor Switch Sensor Indicates Lean Bank 1
The reason I think vacuum leak is that it idles quite rough, and doesn't seem to hold fuel pressure over time. If I go to just crank it on cold start it won't fire, but when I prime the pump (and I hear it working hard to send fuel on first prime), then it'll fire up. And also, rough idle is uneven, it starts idling quite high, almost 2000rpm, but then settles and is very shaky/jerky.
So... do I have to spray the whole intake manifold down with carb clean or is this just a magic fuse issue?
Thanks!
**UPDATE: Tested the Power Distribution Box (engine bay fuse box), 15 amp HEGO fuse was intact. No dice there, sadly.
**Update 2: I forgot to mention it's running very rich--as in, it smells like a lawn mower.
