HELP......engine management light on sri

[lee/sri]

alright ppl

every morning when i start my car the engine management light comes on and splutters at about 3000 rpm after about 20mins its ok for the rest of the day until the next morning. i plugged it into a diagnostic machine and it came up crank shaft sensor (incorrect rpm signal). but i put a brand new crank shaft sensor on before christmas.

Whats the crack?

Can anyone help?!? :twisted:

Thanks!

if u run the diagnostics without the engine running it will give out a crank sensor fault code on some management systems

sounds like sticky idle control valve and management light is coming on cos it cant get the idle down

try removing the valve and cleaning it
