    HVAC Control Unit

    possibly. The one in the picture has auto climate control which I think was only available on grand touring models. So if you can find a more common i or s model it should match up.

    O2 Sensor Question & Help please!

    We have a 14.5 gallon fuel tank, so half is 7.25 gallons. If you get 160 miles on half a tank, that's 22 MPG....the car is rated at 22mpg city and 29 highway. Sounds normal to me. It's not a prius....but it gives a good combination of power and fuel economy for what it is. If you had a bad rear...

    Ok lets do it.... whats the best sounding muffler?

    They discontinued production about a year ago cause no one buys aftermarket parts for our cars. You can still find quite a few new one's floating around online that haven't sold yet. Google or ebay search for them.

    unwillingly sacrificing hp for torque

    I'm at 140 torque to the wheels but 155 wheel hp. It's so low cause I no longer has the VIS system which was in the stock intake manifold which is designed to lengthen for low end torque and shrink for high rpm hp. Best 2 mods I did to gain back torque are the Vibrant 4-2-1 header and the...

    driving issues....

    If you pop 3 CEL's at once, chances are you have fuse that's out. Happened to me while I did a wire tuck. I got 6 CEL's at once cause one fuse went out, including the primary o2 sensor. You can drive on it that way, just don't go on a road trip. It defaults to a sort of limp mode tune if the...

    Oil change Mazda 3s 2007

    if you're in a hotter climate like I assume Panama is, you want a thicker oil anyway and 5w-30 will be fine. That's probably why they don't really sell 5w-20 down there. Oil thins as it heats up, so a thicker viscosity such as 30 weight will be fine.

    Tuning in general 06 Mada 3I

    Intake, header and exhaust on a 2.0 liter will net you about 15hp to the wheels. This will be noticeable, but you will by no means have a fast car. I have a 2.3 liter and I've upgraded - cold air intake, optimized throttle body, header, exhaust, intake manifold, lightweight pulleys, deleted...

    Ok lets do it.... whats the best sounding muffler?

    Couldn't agree more with this statement. The 3 best sounding exhausts on the 3 period. And I've heard every brand in person too. Magnaflow and corksport are deeper toned, the vibrant is more midrange with zero drone. I know magnaflow and vibrant make their own mufflers, not sure what corksport...

    jet power-flo MAF sensor mzr 2.0

    so what were your before and after fuel trims? If you ran a larger TB, intake and cams on a stock tune, I could see that exceeding the +20% LTFT that the computer is capable of adding to the MAF reading.

    Weapon R intake manifold

    Thought I'd add a video in cabin of how the intake manifold sounds for you guys. This is the intake noise, you can't hear the exhaust very well over it above 5500 rpms (revving from 5500 to 7300 here)

    Street Unit Motor Mount Replacement 3PC

    I wouldn't recommend installing more then 1 mount at a time cause they need to break in for a few thousand miles. If you put all 3 on at once it would vibrate the whole car like an earthquake. For the tranny just put the car on stands and use the floor jack to hold the transaxle in place while...

    P2188 code, what would be better to do?

    Hm. I wouldn't think it's the EGR valve unless it's somehow stuck open. Have you checked the fuses? I had a CEL for an oxygen sensor once and it ended up being a blown fuse.

    Under the hood rattle

    More engine movement = less noise and vibration. So by getting stiffer mounts, you're just going to transfer more noise and vibration into the chassis and make more things rattle.
