well first problem that ive been having recently is when i start my car in the morning its makes sort of a grinding sound, i have been trying to pinpoint exactly where its coming from but no luck yet, 2nd my throttle response is reduced drastically after my car his optimal temperature. 3rd, my idle drops if i roll down both windows at the same time. and finally after replacing all the bulbs in the back of my gauge cluster, the needles still dont light up. if some one can please help me i would be very thankful. thanks for your time guys.

 

the only one i can help with is the window thing. try cranking the wheel all the way at idle and see if the idle drops. that means the idler control valve isnt work, meaning when there is more load put on the engine it should up the idle but it isnt.
