Eric,
I’ve had no problems with the Bosch Platinum plugs (they’ve been in the car for over a year).
I sent you a picture of my distributor. I think it’s a rebuilt OEM.
The idle adjustment screw is still sealed with epoxy. (it wasn’t adjusted.)
After I got home tonight and the car cooled for about 20 minutes, I felt the bottom of the IAC Valve and the tubing in that loop. It was hot meaning coolant was running through it. Pulled the radiator cap. Full to the top of the neck. Squished the top radiator hose by hand. No air, just coolant.
I think I might have an electrical problem.
I had I bypass installed from the positive battery clamp to the main positive connection in the engine fuse box because I suspected that line was not up to snuff. I removed it and reconnected the factory lead that’s integrated in to the positive battery clamp.
Result: car won’t idle.
So, I have to order a couple of things from my Honda OEM parts supplier.
-ground cable
-positive cable
-PCV valve
Probably should have the battery tested also. It’s almost 5 years old.
Hopefully, that nails it.
Take Care,
Chris
