Hi again
1982 SC Stock USA
090 WUR

System Pressure 4.3 bars This has always tested low in the 4 years I have had the car. Even with a new fuel filter. No kinks in the line. I have not taken out the screen in the fuel tank to check for blockage. It looks like adding one shim to the fuel pressure regulator should solve that problem.

Cold Pressure 3.4 bars

5, 10 and 15 minutes all 3.9

Engine temp cold between 18 1nd 20 degrees C

This is off the chart high. Cold starting has been the current issue. It fires right up and then often dies or idles at low and rough rpm. When the engine warms up it does run but has occasional misses on acceleration.

Last week on my way home from work I started it but did not wait for full warm up before leaving the parking lot. It pop and stumbled down the road. It stalled at the second stop sigh and would not restart. I could get it to fire, probably from the cold start valve, but not idle. I had it towed home and got it to run after sitting for an hour. Poor cold running and smoother out upon warming.

I have the WUR out and am tempted to take it apart with a talented technician I work with. What are my options here?
