Engine Mechanical problem
2000 Cadillac Escalade V8 Four Wheel Drive Manual 87000 miles
One morning I started the car & it ran rough & I got a service engine light. I replaced the plugs, wires, cap & rotor. It runs a little better but I still get this code PO301. I can't get it inspected until I get this code to go away. I have a 5.7 L with thottle body injection so it can't be the injector or the one coil. I unpluged the EGR valve & got a low input voltage reading. I unplug the sensor before the MAF sensor & nothing happens. Is this the problem? I can't aford to take it to the Cadi dealer. Please help.
have the same problem?
