sup guys, i have been having some trouble with the old protege, its running like ass

ok so to start i put in a cold air intake, and everything went to hell, the car was falling on its face, like spuddering, and not making too good of power, so i tore it apart and re-installed it, just to make sure it was right, and checked for leaks.

then i took off the mass air flow censor, made a seal and put it back on, pressure tested it, with no leaks. took it out again for a drive, same shit. also running real rich.

so i figure, maybe im pulling in too much air, because i live in maine, and its balls cold, so maybe, just maybe its getting wayyyyy too much cold air, i take it apart again, and convert it to short ram, it helps some, but not much.

so i start to pull shit apart, and check stuff, i went out and bought a new mass air flow censor, cause i thought it might be that, no luck,

so then i go out and buy new plugs and wires, and throw them in, again nothing,

then i took the 02 censor out cleaned it off , and put it back in. nothing again.

now more on what its doing, it kinda lacks power upto 4k, as soon as it hits 4k it revs freely and fine, also the car runs real rich now. it threw a code and the code was p0103, maf or vaf circuit high input. im at a loss for what to do. also it kinda smells like sulfure, maybe thats from the rich condition, but i dunno.

please help, lol i have been trouble shooting this for like a week. and didnt want to post till i was out of ideas.

is your maf facing the right way? also is it around the same place as it was stock?
did u pull your negative battery cable off to reset the ecu after u made the alterations?

THEGOLDPRO

yeah i made sure to put it back the right way, and i reset the ecu when i was done, also it is very close to the stock placement.

are u throwing a cel? is it possible u broke your maf?

THEGOLDPRO

i figured that, so i bought a new maf, and it yielded nothing. also yes it threw a code and the code was p0103, maf or vaf circuit high input. i have no idea what this means.

Ben , isn't your MAF the type that bolts onto the intake piping.

Call the mazda dealer and ask them what the code is...
I am more than sure they will tell you..

It really seems like CA intakes and 1.6L's really don't mix.

Try cleaning it with a q-tip and some alcohol. I had the exact same problem you described (except for the CAI).

I even had the exact same power loss and hesitation up to 4K just like you said, and I thought I was going to have to replace the MAF. But I just took it out, cleaned it carefully (the inside of the MAF has two little wires that are barely visible unless you shine a light into the little tube).

Try cleaning it. Sometimes when you change a filter, some lint and dirt might come loose and get caught by the little wires inside the MAF (I think it´s the wires themselves that actually measure the air coming in).

Also... When I spoke with a mechanic at the dealer, he told me that the sensor thinks that more air is coming in when it is dirty (the dirt or lint caught in the sensor make the air push harder on the sensor). Maybe that´s what causes the "MAF high output" code that you get.

Later,
LOS

Hey goldpro, can you give me an update please? Did you solve the problem, has the code come back?

I just got this code today.

I just got this code today. lol well since then i have added a turbo, lol so i dont have the problem anymore, but when i did, i had a junk mass air flow, i replaced it, and the second one i bought was junk, so i got ANOTHER ONE,and it was fixed.

I went through two MAF sensors. the only times I had problems with them was when I had the injen CAI on. I don't know for sure but I'd think the CAI has something to do with the MAF going bad.

yeah it ran fine, till i put the intake on, then it ran like goat. balls.

Do you have the stock intake box on now?

Hmm, so are you running a maf-less setup? Or is the MAF on the pressure side somewhere?

THEGOLDPRO
05-09-2005, 11:42 AM
its about 4 inches from the throttle body.

Cool. It was hard for me to tell from that pic. I've been thinking of moving my MAF to the pressure side.

Is it possible that the position of your MAF can affect ur engine performance? Im mean stock is like far away from the throttle body just closely above the stock airbox. Is it possible that since the position is different from the orginial setup, it cause you problems.. Also for stock, isn't there another air recirculation tube goes from the engine to the intake tube?? And also its after the airflow sensor...

yeah, i left the air ducting off, just have tube and box, so its not quite and i actually get power

i actually cut the little MAF holder out of the box, so i could put on the intake, ill send it to you if you want it, ill snap some pics for you, it works great.
