FD3S rough idle, won't run normal.
 

Hi guys,

I recently had some problems with my 93 FD3S. The other day I started the engine, let it heat up for 5 min and run normally. I engaged Reverse to get out of my garage, and she started to run strange.

See : If I didn't hit the gas, rpm was between 500-1000.

I checked the MAP sensor, was okay.
Charged the battery.
Looked for unplugged hoses, everything was in place.

The engine is supposed to be 30,000km old.
I have a Power FC, Greddy BOV, PFS Intercooler, MSD plug wires, new NGK plugs, upgraded pulley kit and a big exhaust lol.

Here's a startup video : And here's what coming out from the exhaust :
Thanks for helping me out, summer is long without my beauty.

I know it's another poor idle thread, but I need to know where you guys would take a look after the first steps I've done

How recent were the ignition upgrades/replacements? Make sure your ignition harness is clipped together . Check your plug wires to make sure they are all intact.

What are your vacuum readings if your hold the rpms steady at 1.5k?
