I have a '94 FZJ80 and have never had a single "serious" problem beyond replacing brakes every 40K miles. I have never seen the check engine light and beyond changing the brakes every 40K, I have really only had to have the seals in my front axel changed. I am new to 'Mud, and I was never worried about my Truck until then. I am now seeing problems with the '93/'94 ECUs and other types of electro-mechanical problems--mainly new buyers being told that there is a lot of overhead in just getting it running the way it should. What are some general things an 80s owner should be aware of/worried about? I though these things were unstoppable. Mine certainly has been. But what should I be preparing for?
