First off, I've been a 2 year lurker, never once posted, I've used these forums to fix a multitude of things on my 8 (fuel pump replacement, coils, plugs, starter, SSV cleaning, etc) but I've exhausted all my efforts at this point
Stats:
-04 greddy turbo with 102k miles, and an accessport.
Currently running 6lbs of boost.
-Just had the engine rebuilt 1k miles ago by speed1 in Allentown (with Goopy apex seals)
-coils replaced 2k miles ago, fuel pump 3k miles ago, starter 3k miles ago.
-BHR ignition kit, but not yet installed
My problem has been discussed before on a few threads, but nobody seems to come to a definite conclusion on any of them.
Problem:
Whenever I throw my car into neutral going about 45+mph, the engine doesnt even try to recover, it just dies. At lower speeds, it comes close to stalling, but catches itself before it does. It idles fine when it's just sitting, it accelerates fine, drives fine, but it always stalls when I put it into neutral at highway speeds.
Guesses:
A few guesses include, but arent limited to:
-MAF (i cleaned it multiple times, but maybe it's just old and broken)
-one of the vacuum solenoids (replaced SSV solenoid yesterday, so wouldn't be that one)
-something to do with the upstream o2 sensor maybe? (I usually only get 15mpg highway, which is pretty terrible)
-could it be the battery? (mine is somewhat old, but has a consisted 14v charge)
-not likely, but I have a remote starter (clutch doesn't need to be depressed to start car) and the clutch switch is disconnected
-I have no VFAD. The nipple behind the throttle body is capped
I replaced the ESS sensor, cleaned the SSV, checked for vacuum leaks, and replaced the neutral safety switch. I'm running out of options, and any help would be appreciated
