Idling Woes ('99)
 

Alright guys, I'm finally caving and posting a thread after what seems like an eternity of searching mt and the rest of the internet.

Car is a 1999 turbo, using a Voodoo Box and NB adjustable crank wheel (I know, I know. Keeping it legal for new inspection system). My issues have occurred since I was NA, but have become exponentially worse as of late.

My symptoms

• Car starts up, idles fine (usually). Once warm if you rev it up, it most likely will stumble and sometimes even stall out.
• Slowing down to a stop is almost always a chore. Sometimes the idle recovers but usually will stall out, especially if its a harder deceleration.
• If I shift into neutral to coast or prepare for a long, braking stop... My car will most likely stall.
• I always stall when I press and hold my clutch in while at speed.

What I've tried

• Searched high and low for vacuum leaks, no such luck.
• Reset my idle.
• Cleaned TB/IACV
• In the past year or so of ownership, I've replaced a lot of parts including Cam Sensor, Crank Sensor, Coilpacks, Wires. Just for reference.

I've been trying to keep tabs on all the conditions that seem to cause my car to drop very low in RPM or stall and hopefully that will give you guys enough to provide some insight. I'm pulling my hair out, hopefully you guys can save me before I go bald :vash:

Also, please forgive me if this is in the wrong subforum.

Post log and tune. What firmware are you on?

Was running a MS2e, same idle issues then and now with stock ecu.
