    Default santro CNG Connections

    Can any expert tell me color coding of wires of lendi cng kit?

    Also i want to restore wiring of my recently bought santro exec by removing poorly installed Saadi CNG kit (w/o emmulator & advancer). Where wiring might have been disturbed/disconnected by that inexperienced CNG Mechanic. (He has removed insulation from almost every sensor)

    why I want to remove kit?
    1. Kit is giving amazing pick and average but AC is not working on low RPM.

    2. Also engine race increases w/o any reason on petrol.

    3. Gas keeps on running for 10-15 seconds after engine is switch off.

    It is most likely that the mechanic fiddled with the idle adjustment bolt located on the throttle body, while the engine was running on CNG. Get the the idle RPM adjusted while on petrol at about 800. It should be done by a professional, since I think you might mess-up the situtation. Then turn the engine to CNG and try to adjust the idle on the CNG kit. Hopefully your problem will be resolved. It is also worth niticing that the A/C won't work if the engine RPMs go below certain point like ~500RPM....

    Another important thing is, if you have installed the advancer and the mechanic forgot to connect the advancer return wire, the engine RPM on Petrol also increases.....get the connections checked!

    You may contact the following person to properly address your problem:

    no
    MAP or advancer does not have any role to play with idling. Mixture stiings affect idling especially with AC.

    thanks test driver. Are u sure this is the MAP. Some one on other discussion forum regarding spectra said that this is ISA Sensor.

    Dear, see the updated picture! I haven't got first hand experience with santro, but these sensors can surely be identified by physical examination.....

    thanks for quick response, IAC you mentioned is used for air intake/mixing.

    Thanks to all of those who helped me. I have resolved the AC tripping problem and pick issue. www.zetronica.com was also very helpful in this issue.
