Van running rough 4 and 6 plugs misfiring had wires and plugs put on but was still sluggish thought it was bad gas, but it was drive with lack of power. Then it read o2 sensor, but I changed air flow senior first, got good power but couldn’t run A/C. Got it read again and o2 sensors didn’t show but got P0107 and P0108, so I got the MAP sensor but where the guy showed me it went isn’t correct. I put it on the top of the engine but when I start the van it sounds rough.

These are MAF sensor codes, you need to make sure there is not a leak between the throttle body and the sensor.

Code P0107 - MAP Sensor Circuit Low Voltage
Code P0108 - MAP Sensor Circuit High Voltage

Also, check to see if there are any other vacuum leaks as well. To be clear you replaced the sensor and cleared the codes, correct?
