This is Fox-gal's husband.......


We are car ppl Your car looks ta be a 2gen DSM.

What engine do you have? SOHC or DOHC? Turbo or not? I'm thinking...not.

The stock ECU (comp.) uses a AFM (air flow meter) to "sence" the amount of air entering the engine. The norm. is for them to be mounted just after the air filter. It will have a wire harness that goes to it. In short.......It must be hooked up if still useing the stock ECU. Did you forget to hook it back up when installing the cold air intake ?

If the car runs good again, after reinstalling the stock intake,then it's safe ta say it was the cold air intake that was causing the prob.....The ? is why? I bet it has somthing ta do w/ the AFM not being hooked up right.


The idea behind a cold air intake is ta simply move the filter to a cooler spot under the hood allowing the engine to suck in cooler air. (the cooler the air, the more dense it is) and sense it's denser, your able ta get more air into one spot.

Who makes the intake?

I had a 1st gen DSM and my check engine light would come on if ANY wire harness was left unhooked.

It makes sence that the AFM was NOT hooked back up when the new intake was install. ie check engine light came on..

if you have a pic of the engine bay I can tell ya which I'm talking about.

I can take you as deep as ya want ta go......
