hi all
i have a 94 xj 4.0 .. i noticed there are two switches conntected to the throttel, what are they used for ? i noticed they are three in later models!!
here is a pic of my 94:

and also there is another photo for later models that have 3 switches:

any ideas ? thanks

 

Throttle Position Sensor
MAP Sensor
Idle Air Control Sensor
Those are the one I see there.
Other models the MAP Sensor it's not near the throttle.

 

what he said.

And have you considered cleaning out your throttle body? yours has a nasty patch of carbon in the picture. just saying.......
