![]() I heard somewhere....
Something about the ideal idle on a stock efi 5.0 is 800-900. Is this so, or is it somebody's opinion? Has anyone found that to be true. Mine idles at a consistant 750 as far as the factory tach reports. I wonder if I should play with it and find my cars "sweet spot".

![]() W/ an automatic tranny, in drive, 670-700rpm is ideal. With a 5 speed, it's about 100-150 rpms higher.
Take care, ~Chris

![]() Not "rev" higher, idle higher.
Idle speed is the speed at which the engine rotates when stopped at a light, not the speed it's at in Park. Thus, the proper way to measure the idle speed of an automatic is by putting it in drive. Doing this places a load on the engine, and the speed comes down. If the idle speed was the same for both an auto and a 5 speed, then when you shifted it into park, the idle would go too high. Take care, ~Chris

![]() Thanks, I'm sure you know I meant to say idle higher, not rev higher, lol. I didn't really understand why, thanks, Keith

![]() I know Keith, you're pretty sharp, actually. I just wanted to be clear for anyone else that might read it.
