Any ideas folks?

 

Is there any hesitation or bucking if you take off before its warmed up and no longer running rough?

 

It backfires and hesitates. But once warm its ok

 

I had the same issue. Clean your IAC, and if there is little/no change, look into replacing your upstream o2. I didn't see a CEL until it was pretty much spent, but pretty much the same symptoms.

 

Thanks for the info. Ill do that tomorrow. I know the first cylinder compression is low, but its been running ok until just couple days ago. I was suspecting oxygen sensor. Ill check them tomorrow. Lazy currently. I work on cars all day, last thing i wanna do after 5 is work on mine lol
