I put a K&N on my neon and it ran fine for about thirty seconds then just started jerking for and few seconds and stalled. It then wouldnt start and the Check Engine light came on. I rapped it in a rag and drove home and put the stock set up back on and it drove fine. How can i make it work with an after market filter?

 

Is this the K&N drop in filter?

 

It is just a K&N Cone filter that i put on the end of of the intake tube after removing the air box...the problem was obviously too much air and not enough gas but i thought the computer would adjust to it...is their anything i can do?

 

The PCM should correct the fuel.

 

bad tps. (throttle position sensor)
just so happened you put that on when the sensor decided to crap out.
just my edumacated guess.

 

Maybe its the PCM. I just started driving and it was already warm and i put my foot to the floor and it sputtered to a stop and the Check Engine light came on and it would start again. Should i drive it gently for a few minutes so thte pcm adjusts? How long will it take?
