No, you dont have to change the fuel pump...its just an air intake, its not something huge like turbo... or there might be another reason for your car choking. For turbo on 4speed auto, ive seen few users with their tranny parts blown/cracked, as auto transmission is not as durable as manual transmission.
I would not do it if i were you...no offense tho.

Sounds like the MAF sensor isn't hooked up right, maybe wasn't installed in the new intake correctly, or the wires are lose. Also, an air leak in the intake at the hose clamps can also cause an improper a/f ratio and can cause the "choking". Just double check that everything is installed correctly, that everything is tight, and check that the MAF sensor is plugged in properly.

auto = no turbo

[Zoom Zoom Boy]

auto = no turbo

+1. Automatic=Fail. Automatic with a turbo=Epic Fail.

yea just ask boris

[deandai]

did u remove the resonator?

[Hives]

Its the intake for sure, a sensor is being dumb.

As for the turbo, don't do it on an auto. Thats just a disaster waiting to happen. Don't even think about a manual swap either, it costs too much.

The member Boris bought a mazda 3 auto with a turbo kit already installed, and I think he went through 3 transmissions in a year and a half or something ridiculous like that.

ive got a injen in my 07 sedan auto with magnaflow...i had same problem... was my sensor ...the way our air box is set up the sensor sits in a specific way. but with the intake the wires get stretched to fit on the intake... just unplug it and fix the wire so it has play in it where it connects to the intake.

should work...worked for mine

[marrlboro]

where is it located and why would that help?

[marrlboro]

did all that many times and nothing, had to take the intake out then take it to the dealer ship to replace the MAF, do you think that the old MAF was shot and now that i have the new one i should put the intake back in?
Also the stock filters are made out of paper and this one has oil, and that might cause the sensor to short no?

If the car runs fine right now there should be no issues using a CAI. When you put in the CAI make sure you unclip the harness from the battery box to relieve the tension on the MAF wires.

As for using an oiled filter... won't "short" the MAF sensor, but could foul it if you over-oil the filter. I've been running an oiled filter on my PRM SRI for over a year with zero issues.

Just throwing it out there... Did you install the MAF correctly?

When I ask this, I am wondering if you put the MAF on backwards? I did this to mine and the car would start, choke, gargle and stall. Made sense to me right away... And I turned it around, all was fine.
