I have an idle problem. What could it be?
I have a 1994 Honda Civic. After a cold start, probably after 40 seconds, the RPM gauge starts jumping up from 1000 rpms to 2300 rpms continuously. This happens while being parked and while driving.
Due to some research and advice from other whom have had the same issue, I've cleaned out the air idle control valve for any clogged up junk, the manifold too, looked for any vacuum leaks, and also checked the cooling system to see if there's any air in it. Nothing has changed really.
Today, I had the problem where I turned on the car but it turned off on in about 2 seconds. It will stay on if I step on the gas pedal right after I turn on the car. Also, before it gave me this issue, after every drive and while having on the heater, I always got this smell of gasoline. Does this have anything to do with my idle problem?
Let's keep in my mind that I'm no mechanic. So any help or advice will be very well appreciated guys.
Thermostatic idle air control valve. Very common.
- I have a 85 honda vt700 magna that jumps in and out of 2nd.what could be the problem? It will shift in gear and stay at a fast idle but give it some gas it jumps in and out of gear.let off gas and it will stay in gear.is there an adjustment for this.
- What else could could be wrong? My stereo in my 2002 Honda civic la sedan wasn't working right so I had a friend check it out. Be got it so my stereo would work but now the a.c stopped working. When you try to use it the fans turn on for a second then automatically switch off. The mechanic shop said I need to change the control panel but I don't want to get a replacement then this isn't the issue. Is this all I can do to really know. What else could it be?
- If My Car is overheating and i turned the heater on the temperature remains stable what could be the problem? I have 1998 honda civic it was good a while back then no long Ago it started overheating and i change the thermostat and nothing changed and then they told Me the catilyzer could be clogged and i fixed it And nothing changed the rare thing about this is that when the temperature valve start going up i turn the heater on and it goes back down to halfways. I've taking it to a mechanic and he couldnt fix it… I need help.
