I've had this truck since new and have never had a problem. Miles are 71k. Recently, about 35 miles after a fillup, I noticed that my engine started to miss. This happens mostly on acceleration load, even a slight one. As it goes through the gears if I nurse it gently with the accelerator I can get up up to 60mph where it'll cruise just fine on cruise control on level road, but when the slightest uphill grade is involved it starts to miss and jerk. The same thing happens if I press slightly on the accelerator, and is worse the higher I go on the gears. It is very similar to how a previous vehicle acted when I had a bad spark plug that only acted up under load. However, when I started looking for spark plug wires, there weren't any! Whats up with that?
It starts up like normal and seems to idle ok, but can't seem to handle much of a load. Also, my "service engine" light came on after about a day of this.
Anybody experienced this before?
All help would be appreciated.
Thanks folks.
