Update on the Road Ranger tuneup. I ran the tank down to 8 gallons, and I put 8 ounces of “Cataclean” in the tank. The cute little brunette is about 35 miles away, and I ran it up there and back one or two gears lower than I usually drive, per the instructions. The instructions want you to get it hot and keep the engine at a higher RPM to create maximum flow through the catalytic converter. Too early to see if that was an issue or help.
By accident, but then I duplicated it, a couple times I was driving with the gas pedal right at the point where it’s not accelerating, but it’s not decelerating, just feeding gas for as fast as the truck was going. Although there wasn’t a significant change in power, I did have the sense that one cylinder may be coming in for a little while and then going out for a little while. I already have all new plugs and wires.
With all the things I’ve tried and the advice I’ve received from TRS, I finally came around to a dreaded thought: fuel injectors.
I had that reaction because every time I ever fooled with fuel injectors on what I used to drive, it always started in high three $$$ digits. I had an equally positive reaction when I looked online and realized I could buy a set of six for $35. Ordered. Woo hoo!!
Question: is checking the injectors as simple as connecting and disconnecting the electrical on them one by one to see if it makes a difference in the engine, like you pull spark plug wires? I’ve had to pay to fix them before, but I never diagnosed them.
So here’s the current plan. I’m going to fiddle with the fuel injection wiring and see if that makes any difference, if maybe I have a bad connection somewhere.
The compression test kit came in, so I’m going to try that.
If that doesn’t reveal anything, I’m going to put the injectors in. Is there any way to test if they’re good so I can save the good ones as spare parts?
If that doesn’t get the results, I’m going to temporarily cut out my cat and see if I have just fouled that.
I don’t mind the extra work considering the mileage on this thing (320) and that I’d like to keep it for a long time. It’s a hoot and I get a lot of attention every time I drive it.
I also bought a used Santana CD to ease the process
If anybody has any wisdom/comments on a cylinder going in and out (or anything else), please comment.
