Hi all,

Thought I'd ask about a strange problem I've been having for over a year with my Max... much like what Ham1987 described a few posts ago, in fact. Long after the engine has warmed up, I'll be stopped at a light and my idle will stay up around 1500, as if the automatic choke was engaged. Goosing the throttle will drop the idle back to normal, so it's more of an annoyance than a major driveability issue, and CEL hasn't come on. Friends have suggested maybe it's the throttle position sensor, maybe it's the EGR valve (I did test rather high on NOx at my last smog check)... Any input would be much appreciated. It's a 1995 Maxima SE 5spd, 99K, for those interested.

Thanks!
