Sorry if people have had similar problems but I searched and searched and have not found anyone with a problem similar to mine. There have been several with other issues that seem to be different from mine. Here are the details:
2007 Explorer AWD 4.6L v8 95,000 miles.
Driving fine until about 45-50 mph cruising when the rpm's jump between 1250-1500 depending on the speed. Its typically only a few hundred rpm jump and when I accelerate it goes away, it has a forward surge feeling when it jumps. Seems to be a problem at slower speeds as I can see the rpm's jumping but always around 1250-1500 rpm and no feel of surging.
I have checked all coils which are within limits (all arount .9-.8) and boots all appear to be in good shape. Replaced the TPS (due to it always surging in the same rpm range) which failed to correct the problem. If i turn OD off it appears to not jump around.
I am at a crossroads here thinking there might now be a problem with the tranny or OD or torque convertor? I have to tow 2 motorcycles tomorrow about 200 miles round trip. At highway speeds it appears to be fine. Any ideas anyone! I really need some help. Thanks
