Low idle, pls help
Hello everyone, I have a problem that I do not understand. The car is a 2004 Civic 1.6.
The problem is the relay that stays at 500 rpms constantly, does not oscillate and the engine trembles very loudly. So far I have changed so: engine mounts, throttle, Map sensor, O2 sensor, I checked the antifreeze, Temperature sensor, distribution is fine tuned, new battery ... I really do not know what to check ... Any ideas?
Excuse me the way I wrote but I used google translateThe check engine was on because the air filter was removed

The accident may have jolted a sensor loose. I'm pretty sure those have a CPS. Check to see if that's still in place and make sure you don't have any other engine codes.

Definitely scan to see what codes are being thrown.
In the mean time, you can try and idle relearn procedure: link here
It won't do anything if there are underlying issues.

Re: Low idle, pls help
I have no error code, it was scanned 3 times as 2 types of testers. Every time I changed parts that required disconnecting the battery I also made idle relearn but not as it says there that I have to keep the speed at 3000 rpm. I started the car and left it to warm up again until the electric fans started operating. The point is that no improvement was felt after changing the parts, it works exactly as when it first started after the accident. Tomorrow I will try to change CPS and make idle relearn as it says there. Thank you very much for the tips and I hope to come back with good news!
