rough idle after flushing the coolant
Car: 93 rx7 with 91k miles. rebuilt engine with 1.5k miles on it.
I did a pressure test on the cooling system about 2 weeks ago and found a leak (small crack) on the heater hose near the firewall. (The hose looks like this https://www.mazdatrix.com/product/ho...-eng-to-pipel/.) Today, i replaced the hose and flushed and replaced the coolant. I started the car to burp the cooling system out and the idle is rough now (between 550rpm to 650 rpm). The car feels like it wants to stall but it doesnt. I followed the FSM on how to burp the coolant system but the car still idles rough. Before all of this, the idle was usually around 900 rpm. Any thoughts on what can be causing this or why it is doing this?
