2008 Explorer Loss of Power/Air

[sajerond]

I have a 2008 XLT and we were pulling a pair of waverunners through the Appalacians for about 400 miles. I noticed the Truck felt sluggish thorughout the trip even when not in the mountains. The MPG dropped lower than previous times I have taken them. In addition, I noticed as certain power needs, i.e. hills, I lost air conditioning blower until I began to cruise again.

I used seaform to blow out the carbon residue and while it seemed to blow out a lot of smoke and deposits (I assume), today, I took it up a hill and lost the air conditioning again. Truck feels better but still does not seem to have the 'pep' that I believe I had in the past.

Any Ideas?

hmmm sounds like an electrical issue to me,, as the engine works hard the alternator may not be putting out the current needed and that is why the fan is dropping,,
At the same time the G E M and P C M are losing power, that may explain the engine losing power too,,
