So it's been a few months. I've read all the forums. And I know alot of us have dealt with this issue.
What it's doing:
When you start the car anytime it idles or you hold the pedal around 1500-2000 rpm the idle surges pretty fast up and down. About 300 rpm back and forth. No slow surge. Super fast. Between 1500-2k rpm moving about 300 rpm up and down. Now keep reading before you give me ideas.
Want to note car drive amazing when accelerating and decelerating. I've been driving it around. But if I'm cruising or idling in that rpm range I get that surging. When I'm driving tho it jerks the whole car BAD.
Whats on the car:
Car is a 2000 lx sedan (is manual swapped <not by me>)
1998 d16y7 motor (has a y8 thermo housing No idea why)
All the attachments around the motor are stock 99-00 d16y7 parts.
Oem auto wiring harness.
P2e a12 ecu (2000 d16y7 manual)
Pretty much oem all around
Whats been done:
I've replaces everything accept the water pump for cooling. Flushed the system many times. Changed all sensors. And thermo.
Replaced every sensor that reads air and pressure and stuff like map sensor and replaced tps
Iacv is working properly.
Ground is in good shape
All wiring is correct.
No vaccume leaks.
So now I'm left to believe it's something fuel related. Maybe the wrong injectors from previous owners. Maybe regulator. Not the ecu it's new. I've been through everything twice accept the fuel system. But I did check injector o rings. Those are good. All sensors I've check they're reading right. I'm at a loss and need some help and advice on which direction to look to.
Also wanna not compression is a 175psi accross the board.
