Found an ECM bug? (maybe)

[Teejay348]

I am now having the exact same problem and I have spent the last 6 hours researching and reading. Very glad I found this thread on the forum because what bdowne described with the whole ac on off rough idle thing is EXACTLY what just happened to me when I tried. Not sure if this thread died or not but wondering what came about?

ive had rough idle issues where it seems like its going to die but a lift of the brake stops it .

I will have to check to see if my car does this.

That certainly is a weird idle situation.

I did not pay attention ti it this morning, too early. WHen I stead the car to leave work, it was idling a bit over 1k rpms in drive, it was lower later, I think about 800 rpms. I will see if I can keep better track tomorrow.

My Sonic does the exact same, i noticed ever since i have owned the car and a rental i drove as well did the same thing.

When I first start the car it idles at about 1100 rpm, when I place in drive it drops to about 800 rpm. I have had it idle a little rough sometimes I thought, but it may be that I am not used to 4 cyl engines.

mine idles around 650-720 range then when i turn on the A/C it goes to 720-815 rpm.
