Hi I have a 1989 2.8L v6 and i made a custom air intake for it. I had to take off the Mass Airflow Sensor in order to do this and now when I start the car I have a check engine light. I was wordering if having this sensor off would mess up anything, like create a big problem? thanx

 

No, it's there just to take up space...

It's the main sensor in metering how much air enters the engine so you get the proper A/F ratio. Rip out the junk intake you made for it because you won't notice any difference anyway unless you have some mods that actaully require more air to enter the engine and put the Air Flow meter back in.

 

Agreed! With the sensor gone, the computer is using a default value for airflow so the car can run. And that default value is just enough to drive on (its called "limp home" mode) so you can go somewhere to have the car fixed.

Basically while you may have improved air flow, you hurt the performance big time... try reworking your intake so it includes the MAF.

Hey wait, do you have a Camaro or Firebird? If you have a Camaro, you have the dual snorkel intake- and that's already the "best" intake you can get. (Firebirds don't have that because the Firebird hood slopes too low over the radiator support.)

 

And this is why there should be a licence to own tools,

 

LOL, that's a bit extreme....

Pics?

Did you actually make a new intake manifold system, or are you just talking about a Cold Air Intake?

If it's a whole manifold, then I'd say convert over the speed density (MAP)
Otherwise, you really want to get that MAF back into the air flow

 

Converting to Speed Density for power......heh little backwards eh? SD is great, so long as it's calibrated for your exact modifications. Try to stretch the envelope too far and you wind up with crappy power gains and strange driveability issues...

But six-shooter....yeah I agree...lol trying to fabricate a cold air intake when you don't know what an MAF is. Kinda like trying to rebuild a transmission without knowing what the valvebody is.

 

valve Body???

 

yeah, valve body? wtf is that... I've never seen a valve body in any T5 I own

Nixon, yeah, MAF will tune itself better than MAP, but when you are able to adjust things, MAP is really the way to go!

 

there in automatics only as far as ive ever seen, when friends of mine have there autos built they have the valve bodies recalibrated. what it does is beyond me??????? never owned an auto

 

Haha......well they were joking with me, that I own an auto.... The valvebody is what controls the transmission basically. Controls all the shift behaviors...shift timing, firmness, the action itself....its full of valves, springs, check *****, etc. Im not gonna go deeper into hydraulic trannies, vacuum modulators, kickdown cable vs tv cable, etc

 

LOL, Leo, I was joking... There are no valve bodies in a stick shift transmission. Nixon's right on what they do, though - they control the flow of hydraulic fluid in the transmission, so that it'll shift and all.

 

Good to know, hey anyone want a 2.8 rx7??? needs a cat, and the distributor restabbed, im convinced its off a tooth.

 

2.8 rx-&? of all the motors, why put that one in? that said, how much?
