Anyone ever seen/experience this happen?

I was hooking up a line lock on my car the other day and had the solenoid clicking(working). Then I go to start up the car and it does this. I don't know if it's a coincidence but the car hasn't been able to hold idle without killing itself ever since.

I checked all the fuses, any lose connections, and my fuel system is working like it should.....

Any help would be appreciated... BTW one of the first things I did was disconnect the line lock.

Did you check for DTC's? You checked the fuses attached to the positive battery cable? All the fuses in the Battery junction box and the central junction box inside the passenger kick panel?

Maf sensor plugged in? Any vacuum lines unplugged when you did the line lock?

I'd datalog my MAF to see what's going on there.
