Default Pressure drops to 20 PSI
I drove with fuel pressure gauge attached. Whenever car was jerking fuel pressure was dropping to 20-30 PSI. Fuel system description is pretty confusing. Manual says ECM adjusts fuel pressure based on sensors signals.
Any explanations?
Where is Thermo, he knows everything!
