I can rev it to 3.5

When it comes down it catches at 12ish and idles a bit and craps out.
Also while it is reving it kind of snap crackle poppy. If you can follow that.

Edit: upon crank it'll rev just fine a side from the crackle.
It turned over first try and it sounds strong. It didn't sputter or cough.

What happend before you got to the point you're at now? Did you swap any parts out? I would double check the throttle position sensor and the timing. Sounds like some simple thing is just a little off. Only about 1,000 "simple" things to check

I know.

I just don't know where to start.
Fuel pressure regulator...., I think all you can do is replace it.

Maf....., I don't know jack about adjusting the thing.

Where I was at before this is the car has been down with a bhg and has recently been replaced. The machine work was done and all of the things like the starter and alternator are all new.

I'm kind of at a loss here. It started this morning and ran long ebough to get up to operating temp and then dies.

If I plug the maf up it kills it.

Do you guys think a need a new fuel pressure regulator or do ya think the problem lies in the maf.

Do you have any codes? I also had the same problem with my JDM motor but I had three problems with it. They are

-the AFM was bad(code 31)
-the TPS was no good(code 41)
-the CPS was not installed right

I pulled the diagnosis box and it's coated with some kind of shmaz and looks utterly filthy.

I went and picked up a new fuel pressure regulator. It's a mr. gasket brand that is adjustable. It has no vac line so I don't think it will work.
I'm not sure though.

I may have to hook it upelsewhere.

That's just grease to keep moisture off the contacts. Just pretend it's not even there and run your jumper wire like normal.
