Has anyone ever driven without the Mass air flow sensor? it seems to run fine i just don't want to cause any damage by not using it. Thanks

I wouldn't do it it'll throw the computer off and that's last thing you want is messing with that.

My last one crapped out, picked up a new one and now i still have an occasional hesitation when accelerating. I had drivin it to the store without it and it ran great. should i disconnect battery and reset computer with new one installed?

Ya I would think so that usually what you gotta do so when installing any new electric sensor stuff

on mine i cleaned it the other day and i forgot to hook it back up and it gave me extreamly firm shifts

Yeap yeap haha. It's going to read it has like not enough or to much air. Causing your air/fuel mixture to be off and not causing right explosion in cylinder and cause mis fires. So defiantly don't wanna mess with that haha.

Thanks for the feedback, i will disconnect battery for a while today to reset computer, will let you know how that works.

Sounds good

So i disconnected battery for over an hour, i don't think the comp fully reset as my check engine light didn't turn off. My truck is still stalling every so often and hesitating. As soon as i disconnect the sensor though it runs fantastically. It doesnt make sense to me. Unless i have a wire in the sensor harness that is shorting out or something? Anyone have thoughts? This is starting to really irritate me

Sometimes unhooking battery and reconnecting wont erase everything. I mean you go to a smog shop or like a oil change and have then erase your codes. Or you can try disconnecting the battery and turning key over few times in ignition that may help reset everything.
