Ok, got a problem. Since you all have Integras, you might've experienced this one time or another. Well, when I start my car up, it idles at like 1500 RPM. Then...like SOMETIMES, the idle would drop all the way down to like 400 RPM and then immediately jumps right back up! Not sure what the problem is. It doesn't keep on doing that. It just does it 1 time. Then like maybe 20 seconds later or something it does it again. ETc... And when I drive it, when the Temp needle is not "warmed" up, SOMETIMES, whie in gear, the RPM would drop and it feels like hitting the brakes hard or fuel cut off.

I'm not sure if its fuel related or some sorta sensor related thing. Help!


And also, another wierd problem. One day I was driving, and the car really felt wierd, IDLE and the SPEEDOMETER needles going crazy. And it felt like someone hit the brakes, and then accelerated, then hit the brakes etc... Then it ended. Pretty wierd!

 

been checking ur sparks plug lately? That could be one of your problem. You can open up the cap and clean the 4 metel thing that sticks out as they may have calcium built up. The wires should be change every 100k i believe so as the rotors,cap.
