I am working on my sons 90 B2 which is suffering from low gas mileage and high idle (as much as 2500 RPM). I changed the injectors thinking they were leaking. It still sounded like it was not running right. I put on the fuel pressure gauge and it is running 80 PSI. I assume this is too high as my 88 and 89 run between 30-40 PSI.
I assume I need a new pressure regulator. Any other ideas if there might be another cause for the high pressure. Also the pressure doesn't hold, when the key is turned off the pressure drops to 0 in about 10 seconds.
