Default MAF issues

97 ranger 3.0 auto 4x4. With airbox loosely apart, maf just resting in housing and unplugged, it runs decent, can drive around for half hour in woods bouncing around only cut out once over big bump. Put airbox together and as soon as i plug in maf sensor it dies. Truck has a snorkel and i think it has a ton of nests/sticks in it, would that cause it to die out? It doesnt like to run even w/ sensor unplugged but airbox still together. I even tried a good maf off a known running truck and it didnt change anything

Default Re: MAF issues

If you think the snorkel has a lot of stuff in it, then yes, It would probably run terrible or not run at all. Engine needs air to run. Clear your air intake out and get some MAF cleaner and clean the MAF sensor. Follow directions on the can. Don't use anything on the MAF except MAF cleaner. Do not touch the inner part of the MAF sensor with anything but MAF cleaner. Allow to air dry before assembly. Once that is done, try running the truck again and see if it changed for the better. Also make sure you air filter is clean, if not replace. It is important that you run with an air filter or your MAF will get dirty quickly and cause you more problems.

Removed snorkel, changed nothing. Tried airbox as it should be, slightly apart and then so maf was loose and not seated fully and it runs exactly the same. Im leaning towards it being a bad intake tube possibly? Or a leak on intake manifold. Going to try carb clean trick next time to try and narrow it down
