    Bhai yeh kia la lia????

    Check your AC Compressor, Older civic does not have a serpentine belt so just take off the compressor belt and drive around for a few days. I think your compressor has seized and right now its in the process of destroying the condenser and other stuff..

    2.This should improve your mileage.

    3.Since your car is already running under load because of a seized compressor, it will not shift into higher gear in usual rpm range.

    Remove the compressor belt & check!

    Please don't give the car to just any mechanic. Hondas don't like that..

    You are probably already heating up the transmission & you will heat up the engine if you continue to drag it around like this. Make sure you replaced the ATF with Honda only. ZICs etc DO NOT WORK.

    Tiny particles from jammed compressor get into condenser and never come out and keep destroying new compressors. Better replace it or remove the belt.

    Its a VTI, it must have the port reader unless the engine or wiring has been replaced with OBD1. Look for the ECU behind the center console, trace the wires. The port should be on the left side under the steering.

    history of the AC is that the compressor stopped working around 4 months back, instead of changing the compressor, my mechanic advised me to change the seal of the compressor, hence the ac only cools when the car is in motion. (this doesnt hinder me, but i just gave a background of the ac condition)

    secondly the milage is pathetic.. I get 6km/l MAX without AC and with a light foot.

    thirdly, the gearbox: in D the second gear only changes if kickdown is given to the car, it shifts to third after 3500-4000 rpm.
    Brother if the phenomenon is only with AC on then simply change your compressor good kablo one will cost u 3500 rupees in Karachi.

    For third point check your ignition / spark plug wires and distributor, the car is not getting enough power / current.

    To verify that you can drive on CNG and Petrol the shifting point on petrol would be better.

    For mileage u should first of all clean the transmission filter and change the transmission oil.

    After that check the routine things like air filter, fuel filter, valve clearance and get a compression engine check if possible.

    Is your car powerful enough to go on high speeds like 130 km /hr & above .

    YEs, the car easily goes to 150+

    Ok today the car gave the CHECK ENGINE light without AC too. let me try to explain the phenomenon;

    The car is in D and is driving in first gear, it easily shifts at 2000 RPM, then the second gear needs to streched to 3500 - 4000 RPM to shift to third. and if Kickdown is given during this, the car gives a sort of backfire, or "jhatka" and *POP* comes ON the Check Engine light.

    Did any body mess up with throttle position sensor (TPS),If yes then it needs calibration.

    Acha tell me did you take the compressor belt off ?

    TPS is at the back side of your throttle body. Its a plastic sensor with two bolts and mechanics adjust it to solve RPM issues on CNG. Since you are all petrol, it should not have been touched.

    You can pull out codes using OBD2 device. Alot of mechanics can do it for you like PSO at Aisha Mosque or Khan motors. I have one connected to my civic.

    Honda Civic 99 Is OBD-II Really??? I Doubt It....!

    And I Don't Think You Can Pull Codes Out Of Those Fancy OBD-II Scanners....! As Per My Most Of Knowledge....Its Not OBD-II ...Its OBD-0 Or OBD-1

    Better Retrive Codes Using CEL....! And Tuning RPM Issue Using TPS Is One Of Idiotic Thing I Ever Hear.....! Mechanic Deserves A Kick Right Under His Knees For This.....!

    Pull Codes And Act Upon It.....! Compression Test Motor And Check Your IGN System.....!

    Clean Throttle Body If Needed And Calirate TPS Using Multi-meter.....!

    Brother Honda Defence motors will charge u 1500 rupees for retrieving codes through CEL or OBD scanner.

    1000 rupees for TPS clibration and 1500 rupees for compression test.

    All the above work will take nearly all day.

    For throttle body service and general tuning go to any reputable mechanic at DHA Phase -II Ext and you will get the work done for 1000 rupees after bargaining.

    Have u checked the throttle body and air intake for air blockage is it still block after removing CNG or is it normal ?

    I am pretty sure 99 VTI was obdii. Exi was obd1.

    Pulling out obdi codes r even simple. Just jump the connector and count cel blinks and look for interpretation in diagnostic table. I have it posted somewhere on pw.

    Check pso ayesha mosque or drop by shahbaz ill do it for u
