Been researching for a while and nothing seems to match my issue, so here goes...
Original issue, while slowing down, almost to stop, idle would drop way down so low it would almost die. Then it got so bad after a day or 2 and it would die. No codes or CEL.
A few sources suggested IAC, so I replaced it. I found a source to check old one with ohm meter and it was out of specs. I performed the KAM erase and relearn. This changed problem to a higher than usual idle when starting,but would drop down after a minute. When coming to a stop, the idle rpm is 1500 until about 1 second after stopping. This makes it tough to stop, then when stopped rpm drops a little below 700 and makes you think it died for a second then to normal.
I also replaced the TPS and no change. Confirmed no vacuum leaks. Checked for codes again and got drive cycles not complete message so I got a list of them and performed all of them. Checked again for codes and none found. I'm suspecting egr valve or the new IAC is bad, But open to more suggestions. Thanks.
