So I ran the ECU test on my car and Immediately it did one long pause and nothing after it. It didnt even continue the one long pause. I know code 1 is oxygen content....could this be a likely reason why my RPMs at idle are ridiculously low? They shoot up at about 2000 when I first start the car and then with the more it warms up it goes down to about 250 to 300...

thanks fr any help
