My vaccum hose on my Map sensor were falling apart so I took them off hoping to replace them, but I wasn't able to until a couple of days later.
I drove around with them off and got code 3 and 5 which is the map sensor for obd0. I finally replaced the vaccum lines, reset my ecu but it was still throwing codes and running like ****?
Could I have messed up my Map sensor driving without the vaccum lines??

 

anyone?
