Questions about maf sensor
So I have a 1999 chevy s10 2.2 5 speed. I got it about 2 weeks ago. And it runs fine. But today I saw that the maf sensor was unhooked!! Its got an aftermarket cai and I dont know for how long its been like that.. it runs good only thing I noticed it gets about 16 mpgs.. but weird thing is it didnt throw any codes. And it starts and runs fine. I just connected the maf sensor right now and ran it for 10 miles and didnt really feel a difference. . Any opinions on this? I would think that since it didt have the maf sensor it would throw codes or run like xrap but it didnt!
