After fitting my new Toyo Air Induction Intake kit to my 2005 WRX today the car is running lumpy - it struggles to tick over and when I touch the accelerator it tries to stall and sounds like it is sucking too much air in.
I can get it to higher revs but I have to keep blipping the accelerator bit by bit to do so.
Please help?

Did u disconnect the battery while fitting it ? I done my K&N the night before a remap , but i had to drive to the mapper and it was fine. Do a battery disconnect for a while and let the ECU re-adjust . . . . . . . . then get it mapped.
Get ready for the "put the panel filter back" replies too.

Have you fitted the sensor on also? They should come with the mount ![Wink](https://www.scoobynet.com/images/smilies/wink.gif)
Fitted mine without a remap runs ok gives a flutter effect on drop of boost, but is flatter on the lower revs
Mine is going in for mapping in 2 weeks after a VF22 install that I'm not sure the car was ever mapped properly for.

This is (probably) going to get ugly , but the standard airbox is just a plastic box sitting in the engine bay near the turbo etc with a scoop leading from above the rad picking up heat too. How is that any different to my scoop from my fog cover up into the cone filter seperated from the engine bay by a metal heat sheild ?
Does plastic resist heat better or something ?

The induction kit changes the air flow pattern so the maff wont be reading it correctly, The maff will need re scaling, I had one on a wrx and we plugged it in and it was at max correction as it was running lean so we threw the thing away and popped the OE air box back on and it was fine again.

As mentioned above, pulling the battery does nothing, the airflow/timing learning is still stored on the ecu.
Best induction kit to fit is one that does not replace the maf tube as the maf is scaled for a certain amount of airflow downa certain sized tube, replacing it without rescaling the maf will cause unexpected running.

Stick the original air box back on chap and fit a nice panel filter. If changing has made no difference to the 'noise' you wanted then at least the original airbox will rid you of running issues and possible maf issues in the future. The fancy induction kits (sometimes costing big bucks) make no difference to performance anyway buddy.

Std airbox is good to 400 bhp, the induction has screwed tha maf output and the car is running lean, so don't drive it like that revert unless you are going to get a map sorted to compensate, then you won't be able to take it off again without another remap as the air box will screw things up in reverse.
What size bore does the maf tube have, can you post a link to the kit ?
cheers

Well people - I have a confession to make as I have cured the problem by fitting it correctly ( I had it the wrong way round)
Sorry everyone, appreciate your help
