My Alero starts up with no problems, does not shutter or choke while driving either. After a few minutes of driving it occasionally will try to stall when accelerating from a complete stop(stop signs, traffic, red lights), especially on an incline. I recently had to tighten the catalytic converter to the muffler with some coat hanger wires and a new clamp to hold it in place, and it does not seem loose. I did recently find out I lost a lot of oil after my last oil change. The dipstick indicated the oil barely made it to the letter A in then "Add" portion of Add 1 Quart. The oil change was maybe 2 months ago. I added fresh oil and it seemed to run better, but the problem remains.
Any ideas of a place to start checking/testing? I will be doing a scan at Advance Auto Parts today and bring back any codes I receive.
The car doesn't stall in any gear aside from the first gear and only attempts to stall from a stop/incline. Any information you can provide is appreciated.
This will be updated as I go along.
