Default video of my car running poorly...

cold it wont idle at all really, warm it idles around ~1200rpm.

this video is actually the best it's idled since i finished the swap... i have a nasty exhaust leak that i'm not going to fix. i'm going to install the turbo manifold as soon as i get it running right.



after i goosed the throttle the idle hung around 2500 rpm for about 20 seconds. then i ran out of room on the memory card on the camera...

any ideas why it's idling so bad?

What ECU are you using?

If it's a megasquirt you'll find plenty of help with your idle in the Tuning section.

The motor was rebuilt with forged rods. All the sensors and wiring are from my 1.6 that ran fine...
