I figured it out, check my post below

Allright heres the car specs:
96 EK
97 LS Engine
96-98 EX wiring harness
97 LS ECU

Check engine lights:
P0153-Primary 02 Circuit Fault (Dont know why, its wired up)
P0141- Secondary 02 Circuit Fault (Its not wired up)
P1337-CKF No Signal
P0455 Evap Emission Pressure Sensor High Input (Running rich I believe cause of O2 problems.

THE PROBLEM:
When the car starts. it dies. I won't idle, the car just dies. The car will stay alive as long as I give it some gas. If I idle the car between 1K and 2500, it then flutters to say. Like it will go 1100 to 1200 back and forth fast. You get it? . If it go to 2k, it will go back and forth faster. Beyond 3k the car runs fine except that if I let of the gas it drops a few 100 RPMS real quick then goes down in RPMS normally. I dont know what is causing this. It happened 5 days ago then went away!? But it came back and wouldnt go away
ANY ideas on wtf is going on.

I just changed PCV valve, recheck my CKF wiring, check hoses and wiring, BUT i cant figure it out. My only lead may be a vacuum leak.

Yes I also posted in Hybrid, but responce was slow and since my swap has been in for a few months, I figured after that here may be a better spot.

thanks

when i did my swap i didnt connect all the vacuums so i got a rough idle and it would sometimes shutoff. Check your intake manifold for leaks, and if ur missing vacuum lines there, place your finger over an opening and see if that helps.

 

Did you just do the swap?

Check the map sensor. You may have it switched with that other one.. crap, I forget what is is.. but they are really close and share the same plug design.

the plug or the whole sensor?

 

The sensor. Even with a bad sensor, you wont get a code.

 

try lookin for leaks, vacuum leaks, with carb cleaner...

wonderful...
heh. I'll see if I can borrow my friends from his GSR. that would fit right?
I had to also hardwire the IACV cause it was 3plug on the harness. I did check my wiring on the ECU tho...

To all who are concerned, but probably not. I fixed that damn problem that has been bothering me since (checks first post date) a month and 2 days ago.
Its been a bitch and has caused me several kicking of my own ***.

I ran my friends ODB2 program and had a problem with my IACV.
The wires spliced at the plug were getting no connection. So we sodered them together and like magic......the problem was gone and we threw no code for the IACV. Well I will now conclude this and if anyone reads this later in an archive search, CHECK YOUR IACV wiring.....

rename the title, so people can find it if they do search for it
