idle and Map sensor problems like WHOAH
Hey everyone i have a 89 5.0 with a b303 cam flomaster exhaust and 3:73s. My question is about the map sensor. My car will idle up and down from about 400 rpms to 1500 rpms and sometimes it will stall. I ran the codes and got a code 22 saying my map sensor is out of self test range. Im trying to locate the map sensor but im not sure if i have it. The sensor right next to the vacuum tree on the firewall. But on a diagram i saw it says that it is the BAP sensor so im not sure which it is but either way it looks like its sopposed to have a vacuum line running to it...but it doesnt. Is this bad? If it isnt the map sensor, where is the map sensor? thanks guys.
