Bad 3 bar map, what can i try
Bad 3 bar map, what can i try I have narrowed my issues down to possibly having a bad map sensor it is a efi source 3 bar but my problem is no one locally stocks any of the gm 3 bars can I swap in a regular map just to see if it solves my issue and just get a good quality 3 bar to replace it ?
Its breaking down around 4000 rpms I have checked everything and when it breaks down it makes the map reading go crazy and air fuel goes nuts. I mainly just want to try a map sensor to make sure thats the problem. it is currently 3 bar map tuned SD
