SOURCE: Check Engine Light
It sounds like you may have a failing Mass Air Flow sensor, seems like Ive been seeing these tied together quite often. Its a little tricky but a good repair shop should be able to test this sensor. I dont want to tell you to replace it without having it tested cause they are a bit pricey but check around, you never know. Hope this give youu another idea where to look.

Looked up your OBD II code for your Explorer and got the following: Bank 1 Sensor 1
The possible causes are listed below per Chilton: *same result for all engines available on your vehicle
Trouble Code: P0141 (4.0L V6 VIN E Auto)
HO2S-11 Heater Circuit (Bank 1, Sensor 1) Print this code data
Number of Trips to Set Code: 2
OBD II Monitor Type: CCM Details
Indicators: MIL Details
Trouble Code Conditions:
During testing the heated oxygen sensor (HO2S) heaters are checked for open and short circuits and excessive current draw. The test fails when the current draw exceeds a calibrated limit or an open or short circuit is detected.

I had the SAME thing with my car!! Remove your air bag module its a grayish looking box that deploys your air bags, my air bag light was on but it was on and off. I pumped gas in my car one night and when i went to crank it my car cut right off after a split second. My mechanic took time on it but discover that it was a secrity issue. He removed the air bag module and presto it fired right up. I thought it was a fuel filter or fuel pump. It was just the air bag module, people freaked out about it once i told them what it was....it should be under the passenger seat, i believe u may have to take out the seat to get to it.

po141, may be a bad o2 sensor, rear sensor after converter. the po 141 is low voltage to tps, try replacing the oyxgen sensor first and then reset the codes and drive if the po141 comes back then replace the tps,
