    Default Honda Accord 87 - RPM Problem

    Dear Fellow Pak Wheelers and Honda Accord Owners

    I have a honda accord 87 model, total genuine. Engine never opened. only 68000 km done on the odo.
    Now a days i am having problems with the RPM which is fluctuating very much. When i start my car in the morning, i need to push the CHOK for few minutes. Without CHOK RPM drops immediately and engine gets off. I used Carbo Cleaner, Petrol Tonic etc but of no use.
    Please give me your expert suggestions that why this problem is happening and WHAT SHOULD I DO TO GET RID OFF THIS PROBLEM. I dont want to go to a mechanic as I dont want any CHERR CHAARR with engine.
    Waiting for your expert opinions please.
    Regards
    Imran

    You are supposed to use the choke to start the engine, it has got two positions, full out is choke, partial out is "fast idle"

    Start with full choke, as soon as it fires, push it one click, it will set to fast idle (1000~1200 rpm) - keep it that way until the temperature needle registers at least 1 quarter sweep.

    If your fast idle is not at correct rpm (most likely due to ustadee) then set the fast idle cam, its done with by spreading the adjuster of the fast idle cam. Lubricate it with some oil too.

    Thank u very much xulfiqar bhai. Actually engine gets started without choke but to keep it running, i need to push the partial choke for 10 to 15 minutes until temperature needle is on its half. And the 2nd option is that i keep accelerating the engine for few minutes so that engine gets some heat.

    You shouldn't be needing any choke after like 30 seconds or so
    If it takes your car 15 mins to reach operating temperature you may also have a bad thermostat valve
    And if you have a bad thermostat valve in this car I'm sure you're losing like 70% of the carby's functionality as most of the things in its carb depend on the coolant temperature, actuated by different thermovalves....

    Heating system of the car is working perfectly. In freezing temperature i.e., December, January, i can not keep heater ON for more than 20 - 30 minutes.
    Should i change the thermostate valve?
    As per my poor knowledge i think there is not thermostate valve installed in my car as the fans are automatic and even without fans car takes some time to increase temp.

    the car's cooling system is a bit oversized and will take a bit time to fully warm up, install the original 82C valve - its easy on this engine - abt 10 minutes job - including ciggie break.

    This car does require you to pull the choke to fast idle when the engine is stone cold, Once a little warm the engine will sort of idle normally, the way to do it is to drive with fast idle till you get to a long road - then push it in and drive. That is why you also have a indication lamp for choke in the dashboard.

    This car's carb is pretty basic - almost like a mehran no thermosensors at all.

    @Xulfiqar, i know of a car with an a18a engine, but the accord service manuals do not have any data for that engine, does the same carburetor come with any other engine?

    the general imported model with the 1.6 litre engine had a total of 8 vacuum pipes. - easy to identify and fit.

    The japan domestic or UK delivery models had a true damned nightmare of a vacuum jungle with a big vacuum control box mounted to the side of the car too.

    The EFI version also had vacuum pipes but were about 18 or 20 pipes less than the carby version with the "damned jungle"

    ... In this regard I will say

    SON, you have not seen vacuum hell unless you have seen an old mercedes. - How does vacuum controlled transmission sound to you?

    that vacuum box is my kryptonite if its been ustaadified because they are some restrictors in some vacuum lines.

    The other vacuum hell is a 2E-LU engine with the SU carburettor.

    you will go nuts, bolts and screws too.

    Yesterday saw a JDM 89 Accord engine with hell lot of vacuum pipes and a box with it. Boy it scared crap out of me. Question is what is they achieved by vacuums that modern cars cant? Though l love the application of it in my vacuum controlled rear engine mount

    you actually dont have a problem, Its the nature of the car that you have to use the choke lever to raise it to fast idle when cold. Your "problem" that it seems here on this thread is slow to warm up.

    That points to a bad thermostat valve. Replace it.You can fit a civic 78C thermostat in the housing with no issues too. But the factory temperature thermostat is 82C.
