Then I guess the driveshaft and tail shaft are coming off, lol
Drive gear would be the only thing that would fit the issue now
I think the 2wd manuals and 4x4 transfer cases all used 7 tooth Drive gear, but not sure in 1987
Welcome to the forum
Upstream O2 sensor is not on the list?
They wear out, use up the chemicals inside, even while just sitting, 120k miles or 10 years or so
O2 sensors are not used until engine warms up, so 3-5min on a warm day, is when there would be a problem
Also ECT(engine coolant temp)...
You are right that I am wrong plenty of times, lol, but..........................not in this case
2.3l Duratec engine(2001-2011 Rangers) doesn't have same bellhousing bolt pattern as the 2.3l Limas, 1983-1997
2.3l Lima was used from 1974 to 1997, then as the 2.5l Lima from 1998-2001, and...
The "rule of thumb" you are thinking of is when engine is at 500RPM, and its 1g/sec per Liter
so a 3.0l at 500rpm would show about 3 to 4g/sec
Yours was never at 500rpm, most engines don't idle that low
The 800rpm and 7g/sec looks right but also depends on elevation, outside air temp and...
You can still add a switch to disable TCC when you want, I would add a RED led on this switch so you know its OFF
Reason being is driving habits, you can set TCC for 35MPH for example, if you were to "Floor it" at 40MPH you would not get as fast an acceleration with TCC locked, because there is...
Yes, that's a new one
Check if you already have one, I doubt it on a 2.8l but maybe
Ford was adding VSS for cruise and computer use in the 1980's
You will need to get the plug-in for it, as said wrecking yards will have the unit and the plug-in, but plug-in is available new as well
I think you would be better off with a speed switch vs vacuum switch

Expensive but would do what you need, ground TCC solenoid above...
Grumpaw have a read here: https://www.scangauge.com/support/x-gauge-commands/ford-lincoln-mercury/
Looks like Ford changed communications protocol in 2008, so you may need to change ScanGauge settings to get TFT
It is there, for sure
TFT sensor is connected to pin 29 on the PCM
There are 4...
