Hi, I have a 1993 Honda Civic ex 1.6 vtec D16Z6 SOHC engine with 164,000 miles on it. When I turn the car on it revs up normally. As soon as it gets warm the idle drops to 800pm and it starts to fluctuate from 800rpm to 1300 rpm. I, ve bought new the Idle Air Control Valve and also the Fast Idle Thermo Valve but the problem doesn't go away. Is there anything else I should be checking? Thanks in advance for your help.
have the same problem?
