Slow car...

Ill buy the correct one from deloreango in a while. Ill change the fv hoses and adjust mixture for now with a dwell meter. Can't afford it at the moment. The car sure is a money drain. 🤣

And I guess there is no core return since it is the wrong part number.

Thats the cost of restoration and maintaining vs a daily driver where you only fix the absolute minimum to keep it on the road to the junkyard.

Bought my self a multimeter that has dwell reading. Connected it to orange wire in blue bulkhead connector and the other to ground. Put it on 4cyl and dwell reading. It reads about 45 degrees no matter how much I adjust...? Read in the resources that I wanted to adjust it to 40 degrees.

I'll assume that's on a hot running engine.
It should be about 54 deg on a cold engine OR with the throttle spool full open switch is pressed closed (the one that the circular throttle spool presses)

If it does go to 54 deg with the switch pressed, check that the oxygen sensor is actually connected at the electrical connection behind the grey bung at the firewall under the widen boats behind the drivers seat.

It does go to 54.. I will check connections...

Both connections are connected and it goes to 54 when pressed.

A cold engine will run open loop at 45 deg. (50% duty cycle) until the O2 sensor warms up and puts out around 0.5 volts.

If it's really cold then you get the 54 deg (60% duty cycle) until the thermal throttle enrichment opens.

So your not running closed loop if your engine was warmed up. Open O2 circuit or maybe a rare lambda ECU problem. Lambda ECU failure is rare.

Engine is warm, running for 30 minutes, I dont think the fans started, but still hot. So.. Check 02 wiring then?
