Hi guys,
My son and I picked up a 2001 Camaro V6 A4 T-Top SOM car for cheap as my sons first car. Overall the car is in good shape, runs good but runs rough sometimes. Car has about 152,000 miles on it and the engine has about 80,000 miles or so.
I changed the fuel filter and checked the fuel rail pressure and it's reading about 40psi at idle. If you pull the vac line off the fuel pressure regulator, it jumps up to about 49 PSI. I did other basic maintenance on it as well, plugs, wires, oil change, cleaned MAF, etc...
What is the idle fuel pressure suppose to be at with these cars?
Car is 100% stock as they come.
Thx,
Bill
