i have a 94 prelude vtec. my clutch pedal pressure keeps dropping especially when i go on the highway. if i go for a long time, my pedal will fall all the way to the floor. i have to use my toe to get it back up and pump it until there's some pressure again. but this cycle repeats. i just replaced my master cylinder(rebuilt) bout a month ago and clutch slave cylinder about a year ago. i did notice shortage of brake fluid but continues after refill. this just started happening. the brakes are fine.

i replaced my fuel filter and add fuel injector cleaners but my car still runs weaker than usual sometimes. and sometimes when i get a light/stop sign and go to neutral, my rpm will drop and bounce back and forth for about 5sec. sometimes it will go too low and stall(in neutral), so i have to give it a little rev. this happened about a month ago.

does anyone knows how to fix these problems?

clean out your throttle body and the IACV, then use the posted "FITV idle bouce fix" or something like that, a quick search should turn it up, just re-tighten the plastic screw on the back of the FITV
