Hello, a query, I have a Motor Ranger 2.3 year 2006, the problem is that when I accelerate the truck, the pistons begin to head or commonly called "Valvuleo" but fed The problem.
What can it be? Before he didn't behave like this.
By way of help I can tell you that next to the PCM Control Unit, in the same cable branch, it goes a lead pin, which has the function of delaying the ignition, you must disconnect it and notice the change immediately. Danirisa
