Well I drove down to Rogers last night and borrowed Pat's (tehehodi) CAS to see if that was the cause of my hesitation. No change
... so I narrowed it down to be a fuel injector issue now and went down the line unplugging injectors one by one while idling and everyone i'd unplug would make the car stumble until I got to the last one and there was no change. I ohm'ed all the injectors out and all tested 5 ohms (Bosch 1600's), I don't suspect it to be injectors because they are new, now I am going to see if I'm getting any signal at the injector from the ecu.
Edit: No dice went out and tested it I'm getting about 3v at every injector connector at idle. I do hear a slight change in idle when I disconnect the #4 injector but not as much as the rest. Dead/clogged injector?
