engine ligth is on: pepboys ck. failed AF sensor vacuum leak in engene fuel injector or pressure regulator
which parts are we after? fuel pressure regulator? what else?
I'd start replacing those black, cracking and leaky vacuum lines, control hoses and sensor hoses with gates rubber silicone ones....and your ECM will get a fair shake with good data from all the devices in question...the fuel pressure regulator especially~
Get the codes read. Write down the code numbers so you know what parts are failing.
