I have a 2000 Catera with a brand new engine that I installed about 8 months ago. I got a brand new crate motor from LA it was suppose to go into the 2002 Catera. The car has been running great with no problems and since the new motor is a 3.2L I have quite a bit more torque. My problem is when the car is stopped or in park! The idle is low and there is a very small knocking noise which I persume is from the low idle. I would really like to know how to adjust the idle I'm currenlty running around 600 RPM in park but when I put the car in neutral the knock goes away and the idle comes up to about 800 RPM. Any help would be greatly appreciated. Also does anyone know what the idle should be!!
