So I put the test lamp to 87e and the ground. It lit up with the acc turned on, stayed lit whille engine running, stayed lit during the stall. Not even a flicker. I tested 3 times just to be sure. It seems to have an irradic idle at times. However, I notice that it's taking much longer for the car to stall. It ran for more than 5 minutes between stalling.

Just stalled again. Just a thought, the idle switch looks a bit corroded, would that be suspect given the symptoms? Testing that is simply continuity correct?
