what is the big black sensor at the throttle body end of the UIM as seen in the pic? come to think of it, whats the blue one too.
I had a really bad stuttering problem the other day, and the car wouldnt go more than 10feet before it would cut out. The idle was really high too. I then noticed a really loud bizzing noise from the engine bay and after disconnecting a white plug that goes into this black unit the buzzing stopped and i was able to drive the car again (limped it home as didnt want to do any damage with the sensor detatched). the revs were a little higher than normal at 1400rpm but nothing like as bad as the 2600rpm it was before i disconnected it.
Anyone have any ideas as to what it does and why it would make my car do this.
Black is idle speed control valve.Sometimes on Apexi\'s they prefer to run without the idle speed control valve plugged as idle won\'t drop enough.
Blue is airtemp sensor.
