Stumbling @ idle intermittently. 97 w/wire over plug

[45ROB]

Hello to all,
I have read several threads on misfires and repair suggestions, that said I've replaced ignition components and filters.
Here's my situation, the engine stumbles at idle intermittently, then while accelerating it feels like there is a misfire or sticky injector ( loss of power) and then suddenly the condition clears out and normal power is restored. I've had intermittent O2 codes p0140 0141.
Thanks in advance

Could be a plug or coil on its way out or even a fuel injector. Hell it could even be a faulty mas air flow sensor. No mis fire codes i assume?

Without any special scan tools its just a matter of starting with a good ole fashion tune up and go from there. Others might say differently but I’d stick to motor craft plugs from rockauto. There about 5 bucks each or so. Very easy to do. Just take your time and dont rush it.
