I have a 95 Wrangler 4.0 It starts and idles fine, however after driving it starts sputtering like it is not getting fuel. This only happens when driving if stopped and idling it runs fine. The problem is not constant and only seems to be happening after diving a short while, after 10 to 15 miles, and seams to do it more in the mornings when itís cooler out temps in the mid 60ís, never seams to do it on the way home in the evening. I can clutch it rev it up and to about 3 grand and it will pop and back fire for a few seconds and then start running fine again for a few miles. This always happens after riding at a constant speed. What I have replaced; Plugs are less then two years old and are Bosch Platinum Plus, in the last few days Iíve replaced, the Plug Wires, Cap & Rotor, and then the coil. And Iím still chasing my tail. Can you help? What am I missing????
