Hi all,
2006 8.1 Horizons
Engine starts ok, maybe slightly slower than other motor, but certainly starts ok. It then idles around 650RPM. Cruises fine, develops power fine.
However, if left in neutral and set to 1000 RPM, the motor surges in the 800-1200 RPM range.
I've attached a video. The first part is at idle, you will then notice when the RPM start varying after the throttle is increased.
IAC swapped with good engine this morning. Same result.
