I have a 1991 Integra LS OBO0 with a B16a. I have been noticing that certain things i do affect the idle on the car. The first time i noticed it is when i pressed the brake pedal the idle would drop. Then today i noticed that when i press the switch to lower the driver window, the idle dropped and the cluster lights and clock dimmed. When i pressed the passenger side window switch the idle would drop and lights dimmed but not as much as the driver side switch.
I also notice when i start the car the lights dim.
I recently purchased a new battery, which i thought would fix the problems but it hasnt.

Also weird thing that happened today. I had the car on four jackstands while doing maintenance on the car. When i turned on the car to make sure the car didnt have any leaks i noticed the driver side tire turning, when i went to the passenger side that tire was spinning faster. I went into the car and made sure the car was not in gear, and it wasnt. I pressed the brake pedal and it stopped the spinning. They didnt spin again afterwards. Anybody know how that is possible?

 

Did you check your alternator cause your car is giving out correct?

 

As mentioned, have the cars charging system, [alt.] checked, you can have that done for free at any alt./batt. shop, [Interstate Batteries] it takes about 30sec. 94
