I have a 1996 D1 (without AEL) that's running rough (especially on cold starts) and showing P1171 and P0300 codes. Will be doing a smoke test to check for vacuum leaks within the next few days.
My fuel pressure reading is 36 PSI (motor off). At idle, pressure drops and fluctuates between 29 psi and 31 psi. Are the fuel pressure reading normal? Could this be a sign of a failing fuel pump?
I don't know if it's related or if it was a coincidence but the symptoms seemed to occur after changing the PCV hoses.
Thanks!!!
