After I'd replaced the water pump and timing chain (as well as putting a new timing cover on), I thought I'd have better acceleration issues.
This too, was also after I had installed brand new spark plugs and a new air filter.
However, I have noticed that I still have acceleration issues. For those in the Pacific Northwest (Washington state, specifically), if you are familiar with Highway 101 and Highway 104, you're likely familiar with the long climb out of the southbound Highway 101 exit to eastbound Highway 104 towards the Hood Canal Floating Bridge. For those not familiar, it is a long, uphill climb of roughly 10-15 percent grade (Google Earth pegs the grade at 21%!) for roughly two miles.
You begin the climb on an S-curve exit that crosses over Highway 101 approximately 20 miles south of the town of Sequim, after which the highway follows a broad curve to the left to begin a steep, straight ascent with an elevation gain of almost 600 feet. The total distance of this particular stretch (from exit to peak elevation) is approximately 2.19 miles.
Last night, when I was driving home from the town of Sequim, I took this exit and maintained the posted speed limit of 60 miles per hour, in fact I managed to exceed that by about 5mph for one half of the climb up to the top of the hill (I had been passing a slow-moving truck). At about halfway, however, I suddenly experienced a loss of power. The engine did not rev which to me, did not indicate a transmission slippage, even in spite of having my foot to the floor to try and engage the passing gear. By the time I had got to the top of the hill, my speed had reduced to 35 miles per hour and I had resorted to driving on the shoulder to keep from impeding both the truck I had just passed, and another vehicle following behind it.
This was not a 'new' scenario, too. For months I've noticed that my acceleration isn't as robust as it used to be when I bought the Explorer three years ago. When I try to pass slow-moving vehicles, the passing gear will engage, however my speed does not reflect it. In fact there have been times when I try to pass other vehicles (and seemingly engage the passing gear), however my speed sometimes slows down and in those cases, my engine RPM will often stay constant , increase slightly, or act like it's starved.
My Explorer is a 5.0L V8 with the 4R70W transmission. I am at a loss for this and I really hope it isn't the transmission.
What could cause this?
