That lingering hot idle problem with my '88 Formula, which caused me to replaced numerous parts and spend untold hours trying to cure, was due to a bad part right out of the box. It was a Delphi 02 sensor that was causing the car to idle erratically and stall when it got hot.
I replaced it -- on a whim -- today with an NGK 02 sensor and she's running absolutely perfectly.
FINALLY!
I just have one more job to do and it's a pig of a job: replacing the TCC solenoid.

Anyway, the lesson I learned here is never trust any new parts ever again. Just because you took out an old, bad part, doesn't mean you fixed the problem. You could have installed a new bad part, like I did.

I believe that Delphi is a Chinese product . We use only Denso, made in the USA sensors. AC Delco O2 sensors are also supplied by Denso. Have no experience with NGK but if its a Japan product its probably good. Big difference between quality parts made in the USA, Europe, So. Korea, Taiwan, Japan and those made in China. They make cheap garbage over there.

Glad to see you fixed it. You learned a lesson that seems all too common with Fiero parts available these days. It can get expensive changing every part and assuming they are always good out of the box. Diagnostics point to a bad part but because it was just changed too many people keep looking elsewhere changing other parts. Of course this could result in problems compounding as good parts get changed with other bad out of the box parts. Never ending cycle of failure. Hopefully others will learn from this too!

Here we go again...

The apple iPhone is made in China. If Delphi specs junk, Delphi gets junk. There will always be a price leader in the store and it will always be cheaper than the good part.

Don't kid yourself...lots of garbage made in North America too! There are also some very reputable Chinese companies that produce quality products and have very dedicated customer service. I'll agree that the odds of finding poor quality is higher in China, but assuming the country of origin automatically dictates quality is just not true.

Wait a minute... Denso (aka Nippondenso?) Made in the USA? Not that it's a bad part, but...

With that said...
My Delco O2 sensor failed after a year or two. Told the computer that it was running "full lean" (therefore the computer "compensated" with "full rich".)
I replaced it with an NTK (reputed to be made by NGK) and have had no trouble since.

I specifically asked for Delphi, when I replaced the 02 Sensor. I paid more for it thinking I was getting a better product.
I'd be driving at highway speed and the SES light would come on and then go out. The codes would be 13 and 44. But I checked the 02 sensor with the voltmeter and it was within spec. So, started changing other parts and it didn't fix the problem.

I am not down on Delphi. Every company has bad parts that get through the system. Would another Delphi 02 sensor fail out of the box? Doubt it. I was probably just unlucky.

You not liking the company or the product doesn't make something junk. Apple products may be annoying, but they are hardly poorly engineered.

Too bad you had to go thru all that. I have a air-fuel ratio meter mounted in my pillar pod. If the O2 acts up I'll be the first to know.
Mine is simillar to this one.

Its realy amazing how many of our cars problems arent because they are 30 years old, but because of new crappy parts.

And thats the point.

Delphi is another one that I believe used to be made here.

I've probably had better luck with Denso parts compared to any other single brand. Seems to be sourced from the US or Japan most of the time.
