Message Thanks for the tips. I thought I put info in my profile but perhaps not. Either way it is a 1991 N/A with no mods. Has about 202000 km's

The coolant sensor I switched was indeed the ecu not the gauge.
As for idle, I have gone through the process of idle calibration, unplugging the aac and setting it to about 650, then it jumps back up to 750-800 when plugged back in. It has also never stalled or come close on power loss is when accelerating. Even a sharp release of the throttle won't dip anywhere close to stalling.
I used a vaccuum gauge to check vacuum was getting about 18-20 on idle.
I did have a classic fuel leak from what I read, but it has been fixed and I inspected the rest of the system thoroughly. It was leaking from the small high pressure hose connecting damper to return line. Pump and filter were done earlier this year. I havent check pressure so I will do that. and perhaps just replace the filter as they're cheap anyways.
All relays look fine
