so i just installed the alta intake and i can't figure out y my check engine light is on can some one help me figure this out

 

edit:....i guess this stuff does not make a diff when it comes to the light...still worth a look!!

If you installed the silicone hose, check the connection to the thinggy that sticks out the side....and the connection to the car where you took off the cars orgional hose...I have heard many stories about them slipping off if not trimmed right, and then sucking in dirt for a long time.

 

Part no. 7 where it connects at point 5 and connection at area of number 2 it is tough somtimes to get that clamp on straight in the back.

 

Raven comes through again!!
I guess my response wasn't that technical, but heck, try running multiple windows on a I-Touch looking for diagrams!! I think between the two of us we got my point across....

 

The car will run fine and without a check engine light if the entire airbox and hose is gone. So you need to go back and check all the wiring connections, I'd guess something is unplugged or a wire has gotten pinched.

 

probably the throttle body connection.

 

Without the electrical TB connector plugged in, the car will hardly run, let alone a check engine light. Check other wires in the intake region: just to the left of the intake (and to the right of the cylinder head) theres an electrical connector that sits vertically. It's the baro MAP sensor. check that it's plugged and the wires are not broken: that would cause a check engine light.

 

When I installed mine I forgot to install the throttle body plug back in... also I had a check engine light come on and it went off a day or two later... hasn't came back on since

 

I have seen three cars that had damage to the wires of the baro map sensor what year is your car ?
the three cars that had damage where face lift models.

 

mine is a 04 mcs

checked all the connections they seem to be on the good the throttle clamp was a lil hard to get too but it seems to be on there pretty good other then that i don't know but i'll take somewhere so i can get a ecu read

thanks for the feedback everyone. any other thoughts please let me know thanks
