Hi Guys,
I'm using a manual trans 4g18 waja.
Recently, i found out there the idling speed of my engine is abt 1.2k rpm when a/c is off, but it drop till 900 rpm when i swtich on a/c.
I've try to tighten the idle...
Does any of u saw this product b4? I m wondering if we can DIY this thing ourself. The injector is assemble to inlet manifold through an air intake tube. Sorry could find any picture of this thing.
