what problems can occur if it MAF is not plug in? i can't get mine to do into the airfilter adapter, thanks

 

for one you wont be able to rev past about 2k rpms.

what year is its?, and why can't you get it into the adapter?

 

it will idle like crap, run like crap so on.

 

well the way it is right now is not pluged in, i drove down the road and the only difference i can notice is has a small little back fire on the exhaust (but barely noticable) im pretty sure im talking about the right thing the MAF is the sensor that goes to the factory air induct box right? the reason it won't go in is that the way it screws into the factor box verses its just a spout coming out the adapter, and also its a 1990

 

wait, the pig tail isnt pluged in or yor maf isnt screwed in all the way into your intake lol u confuse me.

 

The circled red part is the MAF (The whole metal piece between the piping and the filter), is that what you're talking about?

 

since i couldn't get the sensor in i unplugged the pigtail b/c i didn't want it to just dangle there and get messed up, and yes the circled area is what im talking about.

 

well if you're driving the car w/o any noticeable problems then odds are your talking about the air temp sensor.

 

i looked at again today and noticed that there is another sensor there and i see one that is the MAF and other other must be the air temp and the air temp is the one not plugged in, so is it ok i leave it out? or will it cause problems if i dont

 

plug it in it tells your ecu the temp of the incoming air which the ecu will use to make adjustments. when the weather is cool you can do w/o it. in the summer you'll defiantly need it to keep your car from knocking.
just plug it in and zip tie it to something near your maf like so.

 

yeah thats exactly what i took off, i will do that first thing tommarrow, thanks for your help

 

I didnt have that on mine. maybe its a sohc thing.

 

i'm not sure my 95 has one on it but my 91 didn't have one and i have never owned a 89 or 90 so i'm not sure... i didn't know those even had them i just thought the s14 and up had them...?

 

i have a 92 hatch with a 91 KA and i have it. also, a little funny story, my roommate has a 90 hatch sr20 and his entire MAF unit has been out for atleast 6 months and his car runs like it hasn't even noticed haha. you can unplug the pigtail and it makes no difference and he still runs 8.5's in the 1/8th.. i just thought i'd share that since were on the subject of MAFs. i've never seen anything like that before.
