That's alright. we don't always learn what the root cause was.

 

Those situations irritate me for sure. The ones I cannot quantify and confirm. I much prefer to understand, acknowledge, and prevent further occurrences...

 

don't we all, but electrical doesn't always work that way.

 

If it crops up again, I've had random dyeing with a fubar TPS. You've done so much, didn't catch if you checked adjusted that or not.

 

TPS is adjusted properly. Reading .83 volts, on a ref voltage of 4.87

I will keep that in mind, and also add it to the list of sensors that will be going in my trail parts kit....

 

They don't like getting wet BTW. Happy Trails!

 

HEGO reads infinite across A/B...... Could be an issue....

Hello, CarQuest.....

 

No O2 heater........

 

Are these wide or narrow band? The local "Auto parts" store asked.... And rightfully, I don't know.....

 

They don't need to know that.

NTK 23553

 

It seems there are two Bosch and two denso o2s listed, one wide, one narrow, for each brand.
Thanks for the part # Cruiser

 

Umm.... NTK 23553 came in yesterday, picked it up, went to install.... Wrong one... Thread size is different, and the plug is backwards..... Can't return it as it was a special order at Napa...
damn it.

Good thing I have a tap, and the correct weather pack plugs!

 

NTK 23553 is the correct part. I once saw a "90" at the wrecking yard that was really a 91, guess you are sure you have a Renix with three bolts holding the throttle body.

 

It is most certainly a 1990 Renix.

 

It won't work. Different operating system. It's mis-boxed.
