Default Bad Idle... WTF?!

So I did the tune up and posted those pics for everyone to figure out the parts.

Two I got in and she wouldnt start. I gave her gas and she roared to life. I drove a few spaces and she bogged downa nd ran like **** until I went to the gas station and put some fuel in her. She ran fine all the way home, out to DENNYS then home again.

Yesterday morning she wouldnt start again. Same routine. Now she is parked at my work, incapable of moving. She idles like **** and when you put her in gear she stalls. CEL is on too now. I checked my plugs/wires/cap and they are fine, havn't checked the rotor but that wouldnt change from one drive to the next. Pulled my PCV hose of and she idles higher but CEL stays on and idle is still rough sounding, just higher RPM. PVC and Breather are fine. Air Cleaner is new and fine. Throttle body is fine and not gunked up. I dunno what to do now.

A mechanic wants $80-90 just to shoot my code, then more to do labor. I asked if I went with labor too would be comp the scan he siad no, he has OEM scanners and needs to pay for them so they always charge... bastards.

Whats your opinions?

IDLE Control sensor?

Fuel system issue? Shes burning rich when she acts up so I doubt it.

Help me out.

Choke problem? If you get it running can you just give it a little gas and bring the rpms up a little to get a fast idle going? If you let it warm up for 3-5 minutes, then will it go?

Check all of your vacuum lines and look all around for things making whistling noises. Gotta plug all vacuum leaks.

Have you checked the timing?

Havn't checked timing nor leaks. There is a slight wistle, but cant recall if it sounded like a vacuum leak. I'll find out tomorow after work. Thats where it rests right now, the aprking lot at work. >.<

UPDATE!!!

I was at work today on my day off when one of my installers came into the office asking about my truck. I told him the situation and he asked if I ahd a minute. I obliged and went outside, popped the hood and started talking motors. We poked and proded and I finally started her up to show him the problem...

NOTHING....

...but in a good way.

Not a studder. She started up, roared to life, and ran smooth. I took her to the corner store, filled the lame tire with air and brought her home. I later went back afn fetched my Mirage from our pakring lot, but the Ram drove fine. Can't help but wonder WTF the problem is...

Has to be something with the tune-up. Maybe the Distibuter is being weird, or perhaps the cap and rotor? Is the cap supposed to sit firmly on the distributer? Mine woblles back and forth on the distributer until its clamped down.

Any ideas?

Damn motor gremlins!
