Problem with my car!
 

So the issue is that I installed today a KN Air Filter but the car wont start from the first time it usually starts the second time but once started there is no problem at all! I dont know what it is :confused:
Edit: This is with the Air Filter sensor discconected if I connected it the car will begin to like jerk around like wanting to turn off and eventually turn off and doesnt start at all. Bad sensor? New filter doesnt match the car? other problem?

Sounds like you may have to try cleaning the Mass air flow sensor and see if the problem goes away.

Thanks for the answer but already done that! its still having problems. I take it to the mechanic and he couldn't find what it is :(

If it ran before you changed the filter and it does not run right now than there is something wrong with the way the new filter was installed or with the new filter itself.

Do you still have the old filter? Put it back in to verify that it runs correctly.

Make sure there is no vacuum leak anywhere between the MAF sensor and the head. Mybe you forgot to reattach a hose?

Ichecked all hoses, no leak whatsoever, I remove the MAF sensor and I clean it but same problem, clarification this is a round 3" air filter btw. I decided to put the old filter back on and Poom magic like new. The point is that today I decided to purchase the panel Kn air filter and what do you think? It works fine! and sounds good! Okay, just wanted to point out that I read about some symptoms about a bad MAF sensor and it says rough idle its one of the symptoms and my car vibrates like crazy in idle and making my memory this sensor hasn't been change so it has aprox 133,000 miles, so to resume things I believe it was the sensor all along.

There is a HUGE difference between installing a K&N filter and a K&N intake!
When installing a K&N intake, there are vac lines that must be plugged and possibly a solenoid that to to be removed from factory box and still plugged in electrically even though it is not hooked up with vacuum lines!

This is why it is important in the details and post pics!

Here you go pic of the intake! Attachment 2093

READ: https://www.mazdaforum.com/forum/new...cs-post-30904/ to learn how to load a pic we can see.

If it's a K&N intake for that vehicle it should be fine. If it's a no-name intake with a K&N filter you may have problems.
You may need to get an air straightener: AEM Mass Air Flow Straightener

Again, vaccuum lines that went to your stock air box must be plugged. Any solenoid attached to your stock air box must be removed from air box and left plugged in somewhere under the hood!

That SRI (short ram intake) will not benefit you. After driving around in the city for 10 minutes or so, you will experience Heat Soak. Which means you will have no power. You will be sucking in very hot air from under the hood which is in direct path from the rad fan. I know, i've been there. You need to create a baffle which prevents hot air from rad fan getting to it which must be sealed to the hood.

Yes and no: if I understand you right you have not changed the sensor, only the filter. It works with the original filter and with the K&N filter but not with the 3" cone. As I said there is something wrong with the way it was installed or the cone itself. The fact that it works with the old filter and the K&N pad proofs that the MAF sensor is o.k. Somehow when you put the cone on not all air gets metered.

Follow Noggin's advise.

See my picture I re upload it! BTW thanks for the advices

I see the pic with the MAF disconnected.
Depending on thickness of tube @ MAF comparing it to stock, you may need an air straightener. You definitely need a Baffle!

Also you need to unplug the negative terminal of the battery followed by a depression of the brake pedal. Leave it off for 10 minutes. Re-attach negative terminal.
Start car, idle for 10 minutes before driving. Now re-learning will begin with new set-up for at least 50 miles of driving.

I understand everything except the thing about the brake pedal!

Applying the brake pedal helps to assure that all electrical juice is out of the ECU.
You want to re-set the ECU.

Sorry didn't get back sooner, but i was busy making up this: http://markenperformance.com/n-8333-...ustang-gt.html and another one that is hidden for Superchips Jeep Trail Dash (visible Thurs night!).
I customized all the pics with my new Adobe Photoshop Elements 11 and inputted it on the web! I included a few links as well.

Thanks buddy I really apreciate yout help! :) btw do you a store where i can find the air straightener?

Not other than the link i provided earlier.

Ok I have almost everything sort out but you told me something about a solenoid, and the obly thing I see is an air hose that comes from the engine and connects to the intake See pic, so I dont get that,and if this benefits you the Intake is the OEM intake of the car with the KN 3" filter
You have to excuse my retardiness but english is not my first language :D

I am not familiar with your particular car but giving you a heads up on what to look for.
I have attched some pics from my Mazda 6 so you can see what i'm talking about. It's attached to original stock box and needs to be removed from original stock box (if you have one - it controls an extra intake flapper that open as you stomp on gas pedal) and remain hooked up (other pic). Mine is green.

I discover something my car doesnt use that solenoid I checked the stock air box and it has no solenoid and I dont see a place where it can be connected so I think my model doesnt bring the solenoid from factory probably because mine is a 2000 model and yours is 2006

Lucky You! ;)
Just plug up your vacuum line.
