A bit of back story.

A while a go I was driving home and the car started to stutter bad, sounded like a Subaru. So I pulled over, checked the wires, and the #1 plug wire had fallen off. PLugged it back in, and ran like a champ. Then FF to this morning. Went to start the car and it idled fine, then stumbled BAD. I can run the throttle up, but trying to take off from a stop almost kills it.

Trouble Shooting I have tried: (It is cold so I might need to retest everything again. :( )

Tried pulling the plug wires.
#4. It just about died.
#3. No change in loping idle.
#2. No change.
#1. Just about died, and picked back up.

The plug wires look like they are on, but #1 doesn't seem to sit in as far as the others, and i've tried everything to get it to go further. It has spark on all plug wires, I can hear it discharging on them when I pull them out...

Hoses are all still on solid. Boost Leak Test would require me to drive to work, and if it doesn't run it won't get there, so I don't know if I can test that easily.

Part of me is wondering if it's the injectors. :( Any ideas what the resistance across the injectors are supposed to be? and do I check the wires or the injectors themselves?

Another thing i just thought of. Recently, it's taken to idling high as hell when I first start up, and holding it at 2k. Then stepped down to 1500, then 1000, then it settles in at 750. But when I start driving it and go to neutral for a stop, it does it again, 2, 1.5, then holds at 1000. It would do that until it got warmed up, Then it would be fine.

Potentially I've got Spark Plugs, Plug wires, coil pack, ignition module, CAS IACS, Injectors, or possible ECU ground. :/ With the way it's acting, I'm worried about trying to plug the wife's Laptop in to check DSMlink 2.5

Currently searching the forums, and checking things on my car, so I am being proactive.
 
Well, I knuckled down and started to get into my car yesterday. I did the vac lines delete, egr delete, so I thought, cool, I eliminated a possible vac leak from the egr.

Today, I bought a compression tester, a NOID light, and a spark plug tester. Pulled the spark plugs, disconnected the fuel pump, and did a compression test. A proper compression test.

110, 5, 5, 150.

Guess what I get to plan....
