Well then it’s just freaky weird. The air cleaner looks fine, and in fact the bad idling occurs with the intake tube completely removed. I don’t seem to be losing coolant because the level is steady. I recently had the oil pan gasket replaced and I’m not losing any oil. As stated before, the only place I saw the creamy oil was a small amount in the intake (near resonator). This engine does not have a PCV, it is built into the valve cover and non-replaceable. Let me tell you what I have replaced since the idling issue began: EVAP purge solenoid, gas cap, ignition control module, coil pack, plugs, plug wires, IAC, and upstream OS.
I drive this car 30 miles each way to and from work daily, mostly at highway speed. It runs normally cool, absolutely no smoke from the tailpipe, and RPM’s seem normal. All fuses are good.
I’m just trying to figure out why the idle is not good.

OK, so here’s the deal. First let me say I’m glad I found this site, it’s a much more pleasant way to talk car troubles than face-to-face at a shop (no offense, but everyone I talk to seems to want to retire on my repair job). So funny thing, I actually found a retired mechanic in my neighborhood that helped me do some troubleshooting. I told him about the idle issues, but I also noticed recently that some oil being blown into the intake looks like “coffee with too much cream in it”, and mentioned that to him as well. He said that can occur when a head gasket fails and coolant get into the oil. He also says this gasket failure can cause the type of idle issues I’m having. So my question to you guys is, does anyone agree with this? Should I bite the bullet and have a shop do the $200 compression check? And if it turns out to be the issue, do I go ahead and do a complete gasket kit replacement? (This car has been great, even at 210K miles and I want to keep it going as long as possible).

I have an Innova 3100 (OBDII) scan tool/code reader. Do you know if this is something that I can use?

I probably should have posted that I’m also a do-it-myselfer, not a professional mechanic. I understand what has been replied, but I don’t have the diagnostic tools. I was hoping to avoid the $250 diagnostic quote from the dealer.
