Anyone experience this? Everytime it gets hot and humid, the car runs like complete ****. The throttle response is noticeabily worse. I am gonna have to check my timing soon I guess and get a tuneup. The car has 40k on it.

I am sure everyone has. High humidity air is less dense and inhibits engine power.

I knew the heat would make the air less dense, but I didn't know humidity made that big of a difference.

Here's my experience:

1st time racing at Rockingham, 4/22/01. Nice, cool, dry night. best time: 15.195 @ 90.88. Mods: Hotshot header, UR pulleys, JWT POP.

2nd time racing at Rockingham 5/18/01, 20 degrees warmer and a hell of a lot more humid. Best time: 15.35 at 90.3. Mods: same as above with JWT ECU.


Heat+humidity=slow

Heat is bad, humidity makes it exponentially worse. Hot, humid air particles are HUGE!!! Don't u notice that the best time for driving is in the early spring, when the air is alwys cool? I love it then. (roads being dry of course)

And let's not forget barometric pressure, another big factor. Overall, temperature and pressure have the biggest effect with humidity coming in third. But they definitely all contribute.

my car hits an acceleration wall around 5000 rpms sometimes. the power drops off like a mofo.
I noticed this happens when its humid.
it looses power really bad engine still races can hear exhaust and intake ,doesn't seem to miss,just slows up real bad can feel it stop pulling and rpms climb slow.
when its cold sometimes I hit 5000 and it goes faster.
when I have my ac on and its humid I cant even pull away from a stop w/o half stalling and no power under 2500 rpm.
had a tune up done after I bought it, not sure about timing. idles at 800-750.
I got car in winter if I knew this I would have never bought it. it is real bad something is wrong.
I hope I can fix it it sucks, ill look at my EGR and crappy I guess. if this causes a civic to beat me I am going to die. HELP ME.

Uhh... those times look pretty consistent to me. You might have lost just over 2 HP at the most...
