My Wrangler started "bucking" on the way to work, half way home quit completely. Fuel pump was my thought. Towed it to my shop, replaced the fuel pump and cleaned the tank. Ran for a day then same problem. This time I noticed that when the "episodes" occurred the tachometer was diving to zero (ignition).
I will save you the story and just tell you what I have replaced so far. Battery and cleaned all terminals and connections, throttle position sensor, cam position sensor, crank position sensor, power distribution center (fuse box) apart and cleaned/checked all connections. Disconnected cleaned all of the plugs and reconnected, same with the grounds through the firewall. Spark plugs and coil.
started and ran fine until you move it. It stalls.
have the same problem?
