I finally mustered up enough energy to repair that funky fuel pressure regulator in the Enigma Volvo.
The car should idle more normally now once the engine is receiving a consistent volume of fuel to the injector rack.
Still not sure if we will be showing the Enigma at the Volvo Club National Meet this fall or not- at least given the virus. We are all vaccinated and I am hoping the case rates have stabilized by then.
Now, on to the water pump replacement.
