I have a 94 SE-R that supposedly has a Japanese SR20 in it.
I recently acquired it, so I do not know much about its history.
It has problems idling, but revs up OK, this happens cold or hot.
I tried grounding the MAF wire, but that did not do a thing.
Sometimes, when I am sitting there the idle can climb up to 2,200 RPm(when cold) then it settles back down and almost dies.
It has half of an AEM cold air intake, and it uses the japanese ECU.

I am thinking the MAF may be at fault, or the idle air control valve.
How do I check these things?
Any other ideas?
thanks.

probably you're air control valve
i used to have a rx7 that had a similar problem and i had to replace a shot bypass air control valve

also check your exhaust manifold/header for cracks and that the primary to secondary gasket is sealing right.
