Could be. Do you have MHD so you can scan for shadow codes? I had long cranks, inconstant rpm's especially after putting the car in neutral it would bounce around and WOT it seemed to bog down pretty bad. I had a couple shadow codes also 2BDE and 2BF0. I'm N55 and replaced the HPFP and the fuel rail sensor and I am 3 months without any return of codes or issues and the car starts immediately even in the cold Wisconsin weather.
