Don't know, I do know I'm getting code 1221 which is Oxygen sensor #1
and when cruising or accelerating It loses power, gets it back, and repeats.
It feels like a bad 02 sensor and it's compensating like it's in a limp mode.
So, I'm starting with that.
I'm also going to purchase Spark plugs and a fuel filter today, to make sure it's not a clogged filter or something.
Either way I'm doing normal maintence I would have needed to do anyway with 220k miles so we'll see.
I suspect a possible relay problem, maybe. If so I have a bag of extra relays from the local yard so if it happens again I'll swap out the 4 possible relays one at a time and see if that does anything.
