I 'm from Johannesburg, South Africa a I own a 2001 Grand Cherokee 4.7lt V8 Limited
This morning I hitched a trailer from work to the Jeep and 800m's down the road she starts to missfire and die. I manage to restart her, and she souns like she runs on 4 cylinders.
Do the code read after engine light comes on, shows P300-P302 which according to decoder is missfire.
I checked all fuses and find that the lighter socket is blown, now I'm suspecting a wrongly wired trailer might have caused a short in the harness... Any ideas??
This time of year everyone is closed so I'll be DIY'ing...
