A little more clarification to the situation of my car.
My initial problem started when I could not rev the engine over 3000 under load. When I was driving the car carefully with 20% throttle I could accelerate the car up to 4-5000rpm. Idle and start up perfect but high CO (9%). I have no AF sensor installed in my car and can only measure at idle.
My system control system pressure was 2.5 and did not change during warm up. In addition my fuel system pressure jumped at idle between3-4 bars.
To address the situation I have bought and installed a reconditioned WUR and my idle fuel pressure fluctuation is gone as well as my control pressure issues have improved.
System pressure is over 6 bars and control pressure (cold engine in FL at 80F) is 2.5B raising to 3.2 maybe more when the car warms up.
I thought my issues were fixed and I took the car out for a spin and initially the car accelerated well with no issues. After approx 1 mile or 5 min driving my problem reoccurred but now the engine misfires starting at 1800rpm refusing to rev any higher under load.
When I let the car run in my garage at idle the car starts up fine and idles great but when I try to rev it higher (without load I can rev to 6000rpm) I see black smoke coming out of my exhaust and my new spark plugs are black. Not sure if this is too much CO or burned oil.








I happy ve reWRU ( no 153) rebuildpppp
