need help on lancer, air filter problems

yo i have a mitsubishi lancer ES 2003, and i put a performance air filter, and it worked fine but then the engine light turned on and the car was like choking or something, so then i go to put my stock back and as soon as i turn on the car, it automatically turned off... what should i do cause now im riding with the performance filter with the engine light turned on. if anyone has an idea of what to do please reply. thanx

try  disconecting your battery negative cable for like 10 min and then try it again.

u might have a disconnected vaccuum line.

this will happen if u forget the O2 censor

 

 

           Hola gst , I from P.R my experience with air filter is that here we dont if the used  air filter because that cause a resistance in the motor. In the mitsubishi if the light turn on that dinndt affect the performance of the car. I have a mirage ls and dindt have flow meter I eliminated the flow meter sensor.The light of check engine turn on but I take the car to the Dyno  that give more horse power and have the check engine light on the car run more fast in that way. Very close menssage use iceman of pvc tube are efectives.

 

does the aftermarket air filter have a mass air flow sensor on it? because if it dosen't the engine will set a code to make the check engine light com on, your local dealership should be able to clear the code and fix the problem. let me know what you find out and if you have any more problems.

BLACKSUNSHINE that cars pimpin man! yeah im going with dissconnn the battery. cars these days are all computers if you know what i mean! the car doesnt reconize it so disconnect it for 5-10 min and then hook it back up that should take care of it.

I installed aftermarket on my 02 es and have not experienced these problems but the kit I put on did not interfere w/ factory sensor box. I'm gonna say you've pulled a plug on something in the sensor box.
