1997 Plymouth Breeze P0171
buddy got a this car recently, 97 plymouth breeze, 2.0L.
anyway, getting a p0171.
so far i have verified good fuel pressure with and without load.(47-49 psi).
we changed the plugs, cause they were black!
replaced the pcv hose(it was dry rotted).
next things i'm going to check are vacuum leaks, and do a map sensor check(i don't think this car has a MAF).
everything i have read up on, people say it could be the up stream 02 sensor.
i don't think so......
what are yalls thoughts on this?
May you fly low and fast
rest in peace JL
