Ok,
Did you just buy the car or did you mess with the injectors?

Can't believe someone would mix injectors. Wait... yes I can.

Look on NASIOC for a set of 440cc injectors.

Do you have engine management or a tune on the car ?

Search would have netted this for starters:

P0457 CEL Help.

Do you have the stock airbox/ram air ? If so, throw it back on.

Read that thread/link and then look for the correct injectors (seen them as low as $100).

I can't get on NASIOC to help you look. But they (boxes and Injectors) are all over the place. I have a buddy selling his box and ram. If you are interested PM me.

Maybe someone else can look on NASIOC for you.

Check on E-bay for a used stock box. People are always selling stock boxes on there after they buy aftermarket intakes. So you can benefit for some others soon be misfortune. !Laugh!

Sometimes you can pick up some injectors also.

Good luck man.
