I got the car in November of 2016 and had a low idle ever since. Before the RPM gauge would bounce up and down I fix that problem. But I still have the low idle problem. What could it be? My engine is a B20VTEC with a JDM B16A transmission. Just to let you guy’s know.
Nevermind I found out the problem. I got a flat head I went to the top of throttle body there a screw I turn left to open while car is on. The idle went up and that fix the problem.
