Idle problem
 

Hi all
I've got a idle problem with my 2005 STI.
Since changing the full exhaust system to a full 3" decat, the panel filter, fuel pump and lamda sensor and won't idle properly!!! It's getting remapped tomorrow just want to make sure it's a mapping problem and not a sensor or something else.

The car has been sat for 5 weeks started 1st time but idles at about 1500-2000 revs. Is this the ecu just been safe or is there another problem?


Many thanks Gaz

just over 1500 is ok when cold.
Blip the throttle and it will drop to 800-1000 after a few mins. If is does not then it Could be a sticking Idle control valve if it varies alot and throws a cel.
