DUDE! Just test the fuel pressure solenoid to humor me!

This is next on the list

Any updates? I just started having P0300 with P0090 2 weeks ago. P0090 was actually present last year for like a week with no vehicle hesitation present. Going to test my Fuel pressure solenoid today at my shop. Although I replaced it last summer and the code for p0090 came right back within 30 seconds. F*CK!

Also wondering about updates, as my car just started doing the exact same thing. P0300 only, sounds like a goddamn lawnmower intermittently. The crazy-bad misfiring will all of a sudden disappear at random moments and the car is boosting and running just fine, then as soon as I shift it comes back.
