The car stalls out usually within a minute of running and sometimes will level out and run. I have read the fuel trim and when it first started it starts at 0 and just slowly falls to -32 and shuts off. I tried unplugging the sensors to see if it would run and it did for a couple days then started stalling again, when looking at the fuel trim it was now doing the exact opposite and was a positive fuel trim and slowly stalled out. With the sensors plugged back in it switched back to a negative fuel trim. The MAP reading also seems a little low it reads about 11” at idle
Before I drop the money on a new PCM is there anything else that could cause this issue? And if I do need to go the PCM route, what is the best option? Junkyard, pre-programmed, or should I just take it to a mechanic?
