So??? And the next time, the time after that, and the time after the time after the time after that it will ALSO be corrosion/water infiltration related. And each time I "fix" something, I break off a fixture/bolt/ piece of s*** piece of 20 year old age and sun hardened plastic, so now I drive a s*** mobile.
Yesterday, it started malfunctioning in another new and exciting fashion. An itinerant shudder under accel, and a P0420 code, accompanied by reduced power. And the forum is packed full of people chunking down thousands for attempted fixes for this very thing that don't work.
Doesn't sound like fun to me.
Electrical issues can be frustrating, but getting irritated isn't going to help - only calm, clear thinking will. You can drive with PO420 and, in fact, we did so on our Prius (of all things) for quite some time. When we break something off that's plastic, we seldom fix it - half the time it's not necessary and served largely to make Americans want to buy it. There are many 80's out there which have been more egregiously abused than yours, for example, in Africa - and they still run fine. Frustration is understandable for sure, and we're new mechanics, and often frustrated, probably by things that more experienced mechanics wouldn't even bat an eye over. But when you get to that point, it's often best to realize that your anger and frustration toward the truck aren't getting you anywhere and to call it a day. Your 80 will be fine. It's not a s*** mobile. You'll get it figured out.
