Hi, my name is Mark and I'm located outside of new orleans in louisiana.
I recently picked up a 94 explorer eddie bauer edition for $300 bucks. the truck had misfires real bad when i got it, turned out the guy that changed the plugs and wires before me didn't have his wires going to the correct cylinders, LOL! anyways i straightened that up quick and the truck ram pretty good for the most part, kinda sluggish. i changed the plugs and wires and it ran alright for a day then it just started running horribly. the rpms were way down to almost 500 and it would lope like someone put a performance cam in the engine. the engine would rock back and forth while doing so. i did some looking around and i found some vacuum hoses disconnected and i repaired them. still having the same issue.
if you keep the truck idling at 1000 rpm it runs good, anything below it lopes and struggles until you get it moving above 30 mph. i talked to multiple people and every said it sounds like a vacuum leak. i plan on replacing all the original vacuum lines with new lines. i replaced the MAF sensor with a new one because if i unplugged my old one the truck would run the same plugged or unplugged. i also replaced the ECT sensor because my coolant gauge never moves further than right before the N on NORMAL. new sensor still doing the same thing, maybe its faulty? I'm not sure. i do have a check engine light on and i read it with an obd and it came up with the codes:
O-327:EGR valve position circuit below minimum voltage/EVP-EPT circuit below minimum voltage
O-539: A/C on/defrost on during KOEO
O-565: Canister purge solenoid circuit fault
C-327:
The canister purge solenoid is plugged in but there are no vacuum lines running to it because the barbs on the bottom have been broken off..
anyone ever ran into these codes before? any idea if 327 would cause the engine to lope??
I plan on replacing the TPS sensor and the IAC sensor too…
