im getting a code 40 and wondering if anyone else has
every gotten that code..
im lost because a code 40 shouldnt exist.
my car starts up fine but when i would rev it up to a certain point
it would do an abnormal idle...
kinda like vrm vrm vrm vrm when i give it gas more the idle goes away
note that i dont have this idle when i start the car.. and after a little bit
check engine light comes on.. it gives me a code 10 and 40

 

help help help
im in a hole and need a hand

 

help help

 

yo yo and where is the intake air temp located?

 

What year/engine?

Maybe it was code 4 rather than 40?

Did you forget to reconnect the IAT sensor (code 10)?

Clear the ECU to see whether either code repeats.

 

i have a b18a1 block stock gsr head 95
and when i give lil gas it goes vrm vrm vrm vrm vrm vrm
rev higher it goes away
but yeah the iat is connected
and did clear the code
still comes on

 

ooo and i dont have an intake air temp sensor i got a short ram

 

help please
