    Default RPM drops when car temperature rises to just below 30% never goes 50%+ my car is civic 1.6 VTI manual

    RPM drops when car temperature rises to just below 30% however temperature never rises above 50%+ my car is civic 1.6 VTI manual, when I start the car drive it for 10 minutes+ car works fine but as temperature rises about 1/4 car RPM drops to 200 and sometimes car turns of. Car also do missing and shaking when temperature is below half and above 20%.... any suggestion guys........

    Not an expert but i would suggest to check IAC valve and fuel line specially fuel pressure.
    Any tests done yet?

    No test done yet. I also think that it might be due to valves but need an expert opinion on that. Thanks bro

    your IAC valve shaft may be stuck when the engines comes to operating temperature. get it serviced by a professional.
