Car starts fine and when warmed up runs like a champ. However, when first started she doesn't want to hold idle and driving is very difficult even after a 5 minute warm up. Is there a FI adjustment or is this a timing or points issue?
Thanks, Ned |

Are you talking about the small can with three vacuum hoses to it? On the passenger side of the engine near or on the manifold pressure sensor? Thats the deceleration valve. Disconnecting a hose creates a vacuum leak and a high idle.

QUOTE(The Cabinetmaker @ Oct 21 2012, 09:14 AM)  Are you talking about the small can with three vacuum hoses to it? On the passenger side of the engine near or on the manifold pressure sensor? Thats the deceleration valve. Disconnecting a hose creates a vacuum leak and a high idle. If the decel valve is plumbed wrong it could cause rough idle speed. You can check the diagrams here http://www.pelicanparts.com/914/technical_...4_20FI_diag.htm If the vacuum hoses are correct then you may just need to adjust the idle speed valve. It is the screw with the spring in this picture. Counter Clockwise will increase idle speed.  You should really consider consulting a known good 914 mechanic though. |
