I am not dreadfully mechanically gifted. I got by repairing farm machinery for 40 years on basic common sense, a lot of luck, and a large vocabulary of curse words! But when it comes to car engines, I am totally clueless. And sadly, I generally have to drive older cars. Fortunately, here in the late innings, I have two grandsons who are pretty gifted mechanics.
In June of 2023, I bought a 2000 Xterra SE. Grandson #2 found it on Facebook and recommended that I buy it. It was love at first sight – even though I would have never considered buying a bright, canary yellow car! The car had only had 2 owners and was in immaculate condition, inside and out. The young man from whom I bought it had received it as a 16th birthday present and had taken very good care of it. The love affair was sealed when I realized I paid about $1,500 under book for it! The painful, bright yellow didn’t look so bad after all!
So “Old Yeller” and I spent the summer on the back roads of Western Pennsylvania, running errands, driving some Amish friends around, and enjoying summer. I was pleased as punch with “Old Yeller”. I thought it was the start of a beautiful relationship.
One evening early in October, about 40 miles from home, when I went to start her, she was idling rough and couldn’t generate enough power to move more than a few feet. I finally got “Old Yeller” to a safe place and called Triple A. I figured Grandson #2 could “pull a code” and get me back on the road.
Grandson #2 pulled a PO325 knock sensor code. Some research and shopping led us to a sensor that could be mounted on the firewall, eliminating a day’s labor required to replace the original. All done – no improvement – same damn code. He tried everything that he could think of and got disgusted. I was very proud of him when he said, “Grandpa, I just can’t figure it out.”
It takes a pretty big man to accept his limitations and Grandson #2 is becoming quite a man!
So, following Grandson #2’s capitulation, the boys towed the car to the more modern of our small town’s garages. I left it there in the fall of 2023 (with instructions to “take a look at it when you have a chance”). I’m easy.
Fall faded into winter, and winter finally gave way to spring 2024. “Old Yeller” sat there on one flat tire, month after month (maybe not a good omen!). I was recovering from ankle fusion surgery and wasn’t too amped up about getting her back on the road. Trout season opened, graduation came and went, fireworks celebrated Independence Day – like Little Boy Blue’s toys, “Old Yeller” sat “in the same old place, Awaiting the touch of a little hand, the smile of a little face.”
“The touch of a little hand”. Sometime as summer began to drift off, the garageman had a chance to look at “Old Yeller”. Following the computer prompts, he decided that “Old Yeller” needed a new computer, and he wanted no part of it. He also suggested that his electronic gizmo was suggesting a grounding issue. As he didn’t charge me for storage or labor – I was OK with him not wanting to go further. Like I said before. I’m easy.
So, I had the Grandsons drag poor “Old Yeller” down to the less modern of our small town garages. Left her there with basically the same instructions – “the other guy says it’s the computer” – “when you get a chance, mess with it.” So, I bought a computer for her (30 day fully refundable, I was born at night, but not last night). Guy replaced the computer – no change, rough idle, no power - PO325 code. I returned it and got my money back. The boys dragged “Old Yeller” back to Grandson’s place and time kept moving on.
I kept thinking about the “grounding issue” that the first mechanic mentioned. Xterra forums on the Internet repeatedly suggested checking and improving all of the grounds on the vehicle. As I said at the start, I’m not mechanically gifted and this seemed like a daunting task. But a chance encounter with a half-drunk, old guy led to a possible solution.
This fellow suggested running a new ground to a tight clean place on the frame. Simple, elegant, logical – I wondered why we hadn’t thought about this earlier.
As the winter of ’24 drifted toward the spring of ’25, I decided that we’d try one last round of “fixes” and then sell her if we couldn’t make her run. I challenged Grandson #2 to wire a new ground. If that didn’t work, we’d try a new distributor. And if that didn’t work – we’d give up.
There comes a point in time where the wise man has to admit that he has to give up.
One rainy, cold day in late winter, Grandson #2 pushed “Old Yeller” into the shop again and started tinkering. While he was running the new, heavy-duty ground, he decided to pull a spark plug – basically just to have something to do. And there it was – a totally worn out, about 20,000 miles over due for replacement, worn out spark plug.
A new set of plugs and wires, a thorough cleaning of the distributor cap, and a new air filter – the old one was so bad it had folded up and was letting unfiltered air through – and “Old Yeller” is finally running! Grandson #2 has driven 2 tanks of gas through her on back roads without her missing a beat! A new set of tires and we’re off into summer!
The moral of the story is this: You can’t totally rely on computers and technology, you have to rely on common sense, too. Or, maybe there are several morals to this story. Another one might be; you can’t judge a book by the cover (or, the car by its exterior). “Take care of the little things and the big things will take car of themselves.” And maybe “Occam’s Razor” comes into play; “when faced with multiple explanations for a phenomenon, the simplest explanation is likely the correct one.” (Or, simple is always good!) Whichever comes closest to the reality, I really appreciate Grandson #2’s hard work and creativity and I hope you’ve enjoyed the story!
But, I really do wonder why neither garage man thought to look at the sparkplugs?
