GETTING BETTER!
Thanks for the lead to the ICM and Coil overs!
I pulled out the ICM and coil overs last night and they were badly gunked up. I cleaned them and when I started the car this morning it was much easier to crank and noticably better, but the problem is still there. I wonder if I didn't clean the parts thoroughly enough or if I just need new coil overs or an ICM.
The car still throws code 18 cam/crank circuit error and the idle is still erratic. Sometimes it jumps around 3-400 rpm with no change to the engine, so there is obviously still an electrical issue somewhere.
Should I start replacing these parts? Or check more connections? Maybe the PCM? WHere is that located btw?
Thanks for the help!!!

I'd rather not pull apart the front of the engine to get to the cam sensor. I did pull off the wire harness and clean it last night.
Is it correct that if the magnet was bad, it would only start 1 out of every 6 times? It starts every time now.
Where is the Crank sensor? I guess I could just follow the wires from the ICM and find...
Thanks!

Lets get this right... You need the right info...
If the cam sensor is bad the PCM will start correctly 1 out of 6 times, meaning it will start with the correct fuel timming... The cam sensor is used as a cylinder #1 TDC reference pulse... The PCM uses the cran sensor for the rest... I feel that you have one of 3 things happening here... The cam sensor is having issues, the crank sensor is having issues or the ICM is not happy..
I believe the code 18 usually results in a new crank sensor, but a time or 2 we have seen where the Cam sensor was the issues...
I think it will take more research, but there are a few that have hit this issue head on..

Have you checked over the grounds just in case? Though it *probably* isn't what is causing your issue, I would definately exhaust all "free" fixes before tearing into those sensors. I'm with jr's3800...cam sensor rarely if ever goes bad...concentrate on the crank sensor. Now, sometimes the crank sensor will get road gunk in it, causing false or misinterpreted readings. Find you some brake cleaner and blast that sensor and see what happens after that.

To spare me the time searching, how do I reach the Crank Sensor? I'd put my money on this being the problem.
Cleaning the ICM and coil overs has helped the cold start with occasional stall problem. I know believe this was a separte issue to the jumpy idle. I'll clean the crank sensor tomorrow and see what happens.
Thanks gents.

Should you have to replace the sensor, you will need to pull the balancer off. You will need a 23 or 24 mil. socket, an impact gun, and a puller.

Crank sensor is loose
Well, I think I found my problem. The crank sensor is not seated and is easily jiggled with a finger. I'm guessing that would be a likely cause to the "Crank/Cam Circuit Error". Thanks to everyone for the help.
This weekend I plan to replace it and fingers crossed it'll be smooth sailing again.
