KA24E-T no idle, maybe missing? Looking for help

Post by Dantetris240 »

Hey guys Im having some issues with my recently built KA-T. It's currently running but does not want to hold an idle (feels like its missing).

Here's the weird part:
If feather the throttle the car will stay running, if i hold the throttle in one spot (anywhere in the RPM range) the car will rev to that spot and stay there for just a moment, then drop down (i'm still holding the throttle). I have to take my foot off the throttle and then go back on it to keep it alive.

To simplify: car will not hold a steady RPM with throttle applied, regardless of rpm.


Car:
89 s13 KA24E w/ stock Comp forged internals
Freshly redone engine harness
550cc Deatschwerks injectors
Garett t3t4/ 38mm wastegate
Emissions deleted (only 2 vaccum lines left)
FMIC, no leaks.
Aeromotive fuel pump 250lph
Isr fpr
Battery relocated to trunk
Bov is blocked off (no planning on running one)
2 stages colder spark plugs (new wires, cap and rotor)
Jim Wolf tuned ECU
New MAF
TPS in spec
IACV and PCV retained

I've tried mostly everything i can think of but i'm pretty much out of ideas.

Ive checked the MAF and TPS and they are both reading correctly. IACV is clean, pcv is clean.
Plugs are BKR8E gapped at .34 (tried iridiums and platinums also, gapped at .34 and .45)

Before its suggested: yes ive searched and searched and followed solutions from other threads with no avail.

Thanks for your help.
