Gremlins i.e. Weird issue in my jeep

[JTHunter]

The only 4x4 I ever had was an '82 Toyota p/u with the 22R engine.  It finally threw a rod at about 190K and got "retired".  About the last 50K on that truck, it had a cracked block that a friend helped me drop the oil pan and patch a curved 4"+ crack under the #4 cylinder.  Despite not holding, the JB Weld slowed the oil loss to a qt. every 4-500 miles.  That truck got so old (15 years) that the floor panels on BOTH sides developed fist-sized holes behind both of the front tires.  Never had any mechanical problems other than the cracked block and a cracked exhaust pipe at the flange that bolted it to the manifold.  We ended up having to weld that sucker twice but it worked.

Imagine my surprise when I learned that all voltage regulation for the F-350 goes through the dash. The faulty solder dash. Some internet rando makes a good living resoldering them. Many problems solved.

My little ford focus, no power in even 1st gear, glowing pipe ahead of the cat, all manner of fuel and air codes. Simple fix, fuel filter.

So many systems interconnected and if it is with the powertrain the computer tries to tune itself out of trouble. I think the next car is going to eat hay.

What almost all owners and hell almost all mechanics don’t get is you have to have a true knowledge of how the systems operate and relate to each other and approach problems holistically.

Being one of the ones who understands this enabled me to specialize in diagnostics and effective repair.

Always back to the basics, fuel air spark, draw a picture of what you think k the power flow in a system is etc. Trace everything back starting with the simple stuff. Being a lazy troubleshooter I often rely on the idea that if is common equipment I am probably not the first victim.  Google!
