aftermarket cold air intake sounds
 

A friend installed my after market cold air intake. But my check engine light came on and it makes a little sound most of the time when i push the gas pedal. . Help please

You have to reset the battery....

Disconnect the battery for 10mins....Reconnect....Start car up...Let Idle for 10-15mins....Then go for a drive and step on it so the ECU can get use to the more air flow.
