Subject:      unstable idle

Hi Dan, Saw your post about the unstable idle. Mine used to do the same thing. I think your problem is the idle to too high. There are two switches on the throttle body, one is a full throttle enrichment switch the other cuts the fuel when decelerating. When the engine is running above 1500-1800 RPMs and the switch is activated it cuts the fuel. At idle the switch is bypassed until the RPMs' are above 1500, then if the switch is still activated it will cut the fuel. The RPM's drop and the cycle starts again. Unplugg the switch and the engine idle will stablize. Probably at a fast idle. First, you must figure out why the idle is fast, perhaps a vacume leak, the timing is off or the Aux air regulator is stuck open. Once you determine the problem and correct it reconnect the switch and everything will be fine. IF you find that everything is OK and the idle is still fast, then just turn in the idle air screw on the throttle body until the idle seems normal (800 -950 RPMs). That should do it. Good luck. Take care.. -Jim Digennaro ---------------------------------------------------------------------------- -- LiMBO, The Late Model Bus Organization, international zzzzzzzzzzz_ |E[__][__]|[_]\\ '82 Westfaila 'GTi' | _ LiMBO| _ || 'The VW DJ' =-( )------( )-== James Digennaro, LiMBO Treasurer, Merchandise sales and Webmaster. 20 First St E-mail: limbo@bcn.net Adams, MA 01220 URL: http://www.bcn.net/~limbo/ LiMBO LINE: (413) 743-1814 'Transporters By The Tunnel' A fun camping event held July ---------------------------------------------------------------------------- --
