Is an M44 suppose to fast idle?

uhm, ken, you're wrong.. sorry. :(
it's not a "fast idle" either. it's a PWM solenoid that regulates idle air. It does increase idle while the coolant temp is cold, but not a lot - not 1300rpm or anything. It might bump it 100rpm or so depending on temp. You probably wouldn't even notice if you didn't know how it worked. It always regulates idle speed depending on load, temps, AFR, A/C, etc.
"fast idle valves" were usually used on lower end cars and were basically just an on/off solenoid. so you'd have a ~1300rpm idle with a cold engine, and suddenly it would drop to normal idle speed. there wasn't any real idle regulation at any other temps either.

Hmm my m20 idles pretty fast when its cold out, probable around 1000 rpm IIRC.ส็็็็็็็็็็็็็็็็็็็็็็็็็Originally posted by blunttechI need you to exfoliate my ballsack

I never noticed it at all with my M42. I can't say I've noticed it at all in the M54. I'll take a look this evening; it's supposed to be around freezing.
That 4.4TT is the only one I've noticed with a real pronounced higher idle speed.Originally posted by Grueliusand i do not know what bugg brakes are.
