I did some research and couldn't find what I was looking for. I have a B18C jdm gsr motor and the motor idles fine but once you drive the car around for at least 30mins the motor would idle very low when you come to a stop. I would say around 100 rpm. The motor would start to shake and not idle properly. I revved the motor up to 2000 rpm and it would drop down to 0 and the motor would shut off.

According to the research I did on HT, one reason would be bad spark plugs, spark plug wires, and the IACV. I replaced new plugs and wires and cleaned out my IACV. What do you know, the motor still idles the same. I don't know what else could be the problem.

If any of you guys experienced the same problem that I am. Please fill me in because I am not getting the power that I used to when the motor still idles at the correct rpm. The motor bogs for about 2 secs when I floor it. I hate it .

 

anyone with this problem?

 

Could be your ignition coil or module going out. They are fine when they are cold but once they get warmed up, they start to act up. This happened to my civic a while back, my coil was going bad, at start up it ran fine, after about 10-15 mins, car would hesitate to accelerate and would die at a stop.

 

thanks i might have to check up on that.
