Good day!
Thank you for your reply.
911 SC euro 1982 no lambda
Will fire up at when cold but when hot after 1 hour will need about 10 sec of cranking. Next morning when engine is ambient temperature will start first crack.
1. New fuel pump and check valve
2. New accumulator genuine
3. Rebuild WUR 089
4. Cold pressure 1.7 Bar @ 18C, warm pressure 2.8 bar and 3.5 bar with engine running. System pressure 5.2 bar
5. Residual pressure 1.5 bar after 30 min. Will keep above 1 bar for more than 4 hours.
6. Tested TTS with battery and test light. below 45C will light for about 2 sec. Above 45C no light. Working as it should. No problem with cold start.
7. CO% level @ idle adjusted to 2.8. Will reduce to 0.6 @ 3000 rpm. HC below 60 at idle
8. Ordered new FD fuel relief valve. I dont think this will solve the problem though since residual pressure is within spec.
9. Will install new injectors, but i have no symptoms that confirm it is required. Steady idle, no Knock during full acceleration.
10. Total Ignition timing adjusted to 25 degrees (pulley notch) with vacuum disconnected.
11. New spark plugs Bosch W3CC
11. Engine runs very well.
I have all symptoms of residual pressure loss but my gauges prove otherwise
Is there anything i forget?
