Re: 96 Ranger2.3 Hesitates from off idle
mine does that now too... I haven't figured out why yet. Started about a
month ago, right as it crossed the 230,000 mile mark. I replaced the O2,
idle control valve, filter and throttle position sensor. It still does it.
I'm thinking it's the pricey mass air flow sensor... the computer says mine
is fine with code 111. Do you have a code reader? What's yours telling you?
