Do you have any exhaust leaks?

+1 on the exhaust leaks. Also check for vacuum leaks especially around the PVC system. Do this before replacing any parts.

>>
For lean and rich DTCs:

• Fuel system
• Excessive fuel pressure.
• Leaking/contaminated fuel injectors.
• Leaking fuel pressure regulator.
• Low fuel pressure or running out of fuel.
• Vapor recovery system.
• Induction system:
  • Air leaks after the MAF.
  • Vacuum Leaks.
  • PCV system.
  • Improperly seated engine oil dipstick.
• EGR system:
  • Leaking gasket.
  • Stuck EGR valve.
  • Leaking diaphragm or EVR.
• Base Engine:
  • Oil overfill.
  • Cam timing.
  • Cylinder compression.
  • Exhaust leaks before or near the HO2Ss.

got the car up and couldnt see any charred black spots on the exhaust or headers. and just curious if it was leaking from where the headers mount to the heads would there be a pretty noticeable sound coming from it? ive sprayed the intake manifold and intake and pretty much the whole engine with starting fluid while it was running and it idled perfect. i also have a p0153 o2 sensor code?...which i just found out :/
