I had a DISA valve o ring that wouldn't throw a code very often but was clearly leaking. It caused idle to bounce around just like yours. Once it warmed up it was fine.

stephen, would that cause a no start?
I found some cool info on the fuel pump for me.

You can rent or buy a fuel presure gauge at autozone. You can check it at the fuel rail.
Probably the fuel pump. Mine went out at about 110,000 if I remember correctly, that is the range... 100-145

Probably not. I never had starting issues.Originally Posted by flavo

Maybe sticky idle control valve. I know it affects cold idle more than anything else. Would be worth taking it out and cleaning it with carb cleaner to rule it out.

Good idea. Mine was stuck in place. Also do throttle body (and DISA ) while you are there.

I ordered the fuel pump, relay and filter this morning. I confirmed that the pump was the original and the filter probably will be too. I cleaned the ICV when I got home and the car is back together now so I won't be tackling the other 2 unfortunately. The DISA I sprayed with some brake cleaner and moved things around before reinstalling but I have no idea if that is what you are referring to. I will do some research on that in a while. I did nothing with the throttle body other then look at and push on the flap/butterfly to see what it felt like.
The fuse for the pump was burnt out and I replaced it but it made no difference. Does it make sense that the fuse would have blown when the pump went out?
Thanks for all the help folks :-)

The fuel pump is super easy, literally pull the bottom of the back up, unscrew 3 Phillips screws, pump is now exposed, remove fuel lines, use a hammer and a flathead screwdriver to twist the pump out, pull out carefully and install in reverse order. You will be amazed how easy and quick it is (45 minutes to an hour most).

I actually pulled the pump out today too just to look at it. It was super easy. I just watched a couple DIY's on the disa and TB. My DISA is fine but I would like to do the upgrade at some point. I really wish I had purchased a lower intake boot though. Mine was fine I think but was showing signs of age for sure. I think I will get one soon and clean my TB at the same time for good measure.
