    REMOVAL
    The EVAP purge solenoid is located to the rear of the engine block, below the intake manifold above the starter solenoid.
    1. Ignition Off.
    2. Remove air induction tubing from throttle body to air cleaner.
    3. Disconnect crankshaft position (CKP) and knock sensor harness connectors.
    4. Remove CKP and knock sensor connectors from bracket by inserting a flat-bladed screwdriver between the connector and clip. Gently pull the connector toward the battery to remove connector from clip. Do not pull on the wires.
    5. Disconnect EVAP purge solenoid harness connector.
    6. Disconnect purge line quick connect from EVAP purge solenoid and vacuum line.
    7. Remove both 10 mm EVAP purge solenoid bracket bolts and remove solenoid/bracket assembly.

    INSTALLATION

    1. Install EVAP purge solenoid/bracket assembly and install attachment bolts. Torque: Canister Purge Solenoid-to-Block: 22 N.m (16 ft-lbs)
    2. Connect purge line quick connect and vacuum hose to EVAP purge solenoid. IMPORTANT: Make sure purge quick connect is seated and a "click" is heard. Pull back to confirm a positive engagement.
    3. Connect EVAP purge solenoid harness connector. Push until a click is heard and pull back to confirm a positive engagement.
    4. Install CKP and knock sensor connectors to bracket by sliding connector into clip.

    hi saturn56

    will try that, as my car (94sl20 works excellent at 450,000Kms besides that sometimes difficult start where i essentially have to apply some gas to it and then slowly release the gas pedal or it will stall....as rpms bottom out

    interestingly - never happens when it is really, really cold ie. at least minus 10 or more...warm weather i know i have to hold the gas almost guarantee and then she runs great no further problems

    it did replace the entire cpu based on one recommendation but it made no difference...got it for 80bucks used so??

    any ideas..sound like the same issue to you?
    thanks...been doing it now for about 1/2 yr but again besides the difficult assisted start it goes fine (it is winter now so will see what the summer brings)....also replaced idle control valve, tps sensor and no difference

    any thoughts would be great...oh yeah i also have a remote car starter
