At what gear are you under 3800rpms. Usually im in the 4200-4600 range and thats in 5th gear. Ever since I did a motor swap and a few little mods I can't get it down to 3000-4000. My car Idles at around 1200rpms. Factory setting says 740. I heard 1000-1250 is safe. Lowest I had it since a few mods was 1000. It's usually at 1000-1500rpms Early morning start. When I crank it over for the first time it jumps usually from 2000 to 3500rpms for about 5min of just warming up. When it warms up it sits idle usually at 1200rpms. I have been adjusting it and adjusting it trying to get it lower, but I can't get it any lower then 1000. It doesn't breath right under 1000rpms now. Even at 1000rpms sometimes the motor sounds a little funny. Sounds like a potato is stuck in the intake. Sounds a little louder and rough. any suggestions ??
