I have an 89 Accord LX Sedan and I`m having problems with the choke in cold weather starts (0 to 15C...for this time of year).
Scenario is as follows:
-Starts up fine with no problem in cold weather.
-I let it idle for a couple of minutes to warm up the engine.
-Start driving with the temp well below normal operating level and the idle at 1600 RPM
-Drive for almost 10KM when normal operating temp has already been reached and choke is STILL closed keeping the RPM`s high at 1600 RPM.
-Every now and again at a stop light I tap the gas pedal to try and disengage fast idle cam with no effect. Idle is still high.
-Eventually a tap on the gas pedal will disengage the fast idle.
This ONLY happens on cold weather starts. Once the engine is warmed up however, no matter how many stops during the day I take (eg, to run several different errands for example) it will run normally with the idle around 800RPM. I should also mention that I no longer have a pre-heater hose that connects to the exhaust and the air intake as it fell apart a long time ago.
Any help is appreciated.
