First, I'll say.. Howdy All !
My truck recently had a full tune up. I think the tune up made this problem more clear...it has a miss (choke,cough, hiccup) under light acceleration or when I feather the pedal to hold speed (no cruise). It feels like it is about to run out of gas. Or, if it had one; like the carb is loading up.
It will do it in all gears. It does not appear under hard acceleration. Tachin' up makes it smooth out, when it does happen. Running in a lower gear and keeping it wound up, is smooth. Shows up sometimes at idle, mostly at steady speed.
I once had a Ranger that lost a catalytic/exhaust sensor. Kinda like that hesitation but, does not die when hot.
Racking my limited mechanic brain. EGR, Oxygen Sensor, Throttle Sensor...Any of you had similar problems or have any thoughts...??
