'12 Voyager 1700 Misses Under Acceleration. HELP!!!

[bwmatt1]

Lately I have been experiencing a miss, or hesitation when I turn the throttle about halfway. It idles fine, it cruises fine, and it's fine under full throttle. But at half throttle it jerks and misses and acts like its totally misfiring. Rpms are usually in the 2500-3000 range. I really noticed it while cruising in colorado. I couldn't just easily accelerate going up hills, I had to give it full throttle. Just changed the plugs...no change. Any ideas? TPS? Injectors? Valves?

I have the same trouble ..
I think the matter is in the ecological compatibility of the system, there is a valve for oxygenation of the exhaust manifold, and there is an O2 sensor.
here he tunes the mixture in this interval is very bad ..
Now bought a blend (system) instead of an O2 sensor and a snag on the valve in addition to air.
Let's see what happens, I'll sign off if you do not block for debts)
Do you have an O2 oxygen sensor?
