  • SES Light Off, Codes stored

    I decided today because i was having idle issues to just hook up one of those cheap code scanners, and it showed code 33 and code 42. But my SES light was never on, then i went around the block and my SES light stayed on, so I pulled the ECM fuse and it went off, but the codes are still there, but the SES light stays off. Now one of the codes was for the MAP so i bought a new map sensor, hooked it up, pulled the ecm fuse but the code is still there, so i just returned the MAP sensor. Any idea's?

    Listed are some parts ive recently changed,

    IAC Sensor
    TPS Sensor
    Cap
    Rotor
    Plugs
    Ran new vac line from vac tank to intake check valve
    PCV valve
    Air Filter
    Fuel Filter

    Ive ran fuel injector cleaner, and checked the fuel pressure which holds steady.
