If the MPS won’t hold vacuum or is set way too lean, your idle will likely hunt no matter what else you do.
Fix the MPS first. |

QUOTE(rjames @ May 7 2025, 09:03 AM)  If the MPS won’t hold vacuum or is set way too lean, your idle will likely hunt no matter what else you do. Fix the MPS first. It's a really weak leak, and with a leak you are actually going rich. Hunting is normally a lean condition. |
