So, this thing typically runs about as well as a Swiss Watch, so problems make me scratch my head.
When I joined this forum a little more than a year ago, the Explorer had 112,000 miles on it. Now it has 140,000 miles, and we are starting to see some minor issues. Today, we had a good one.
It started as I went to merge, and I kinda floored it. Almost as I got to full throttle, it bucked SUPER hard...hard enough to bark the tires, and I was already doing about 40 MPH. After that, the wrench light in the dash came on, and the Trac light came on. It didn't die, or stop running, or even seem like it wanted to quit. I kept driving, and started playing with it....anything over about 75% throttle produced some bucking, nothing serious, definitely nothing like what had occurred.
I got home and went to drive it up a slight hill to my garage, and it really didn't want to go up the hill. My wife told me the front wheels were skidding on the ground (it's icy out right now) instead of spinning or turning. I kicked it into 4H, and pulled gently up to the garage, and it seemed down on power. Grabbed the Bluetooth scan tool and plugged it in before shutting it off, and this is what we got:
So, conventional wisdom tells us this is probably coil packs, and at 140K miles, it probably is time for a set. After a restart, there was no more wrench light, no more Trac light, and the engine had full power.
I don't dispute some coil problems, however, every single cold start when I go to leave, it kinda jumps a little as you give it gas...lurches, if you will. It only does that the very first time you give it gas, on a cold start. So I am also wondering if I am having electronic throttle issues as well. I have previously put an electronic throttle on this car for the previous owner, and it was having a bucking concern at that time as well. However, it had no wrench lights, no MIL's, and the only way I could tell that was the problem was by comparing the accelerator and throttle sensor readings.
What say you?
Thanks again for reading my lengthy post!
