The 2000 Grand Prix GT I got recently has a high idle in my opinion, when it's first start after cooled down completely, like when it sits overnight. The idle is normally around 1700 RPM's. The idle comes back down then after 30 sec, maybe a little less. The reason I think its a little weird is because my brother has 1998 grand Prix and even on the coldest days it really doesn't go above 1250 RPM's. Also whats weird too is that it doesn't have to be cold outside either like 70-80 degrees it will still do it. Kinda afraid to see what it will do when it's 20 degrees out. Now when its warmed up or even a little warm it's totally normal. The only reason I'm asking is because the other Grand Prix doesn't do this. What do you guys think?
