1996 Honda civic ex cuts off when driven hard.

[young_]

So this has happened a few times, and it happened again today. I have a friend that lives way out in the back woods and I was having some fun (a lot of fun) and when I pressed in the clutch and braked to slow down, my rpm's dropped straight to zero and the car cut off, I switched to neutral and cranked it back up but it cranked slow and took longer than normal. I did some routine maintenance on the car that I had already planned to do (replaced the fuel filter and ran some fuel treatment) the car ran fine, idled at 800 (even when holding the clutch in all the way when riding). I drove it a little spiritedly and then the rpms dropped down real low almost to zero and would climb back up to 800. Any ideas as to what it is?

Car has all new plugs, wires, cap, rotor fuel filter, 4-2-1 header, and AEM cold air intake.

Any and all help is appreciated!

did you fix that vaccum leak?

Yeah and that seemed to fix it at the time but I guess the problem is just intermittent

If a mod wants to change the title to "car cuts off when clutch is pushed in/ low idle" they can. It's doing it every time now, but as soon as I crank it back up it stays running but just at around 1-200 rpm. (Low!)


ANY ideas? I swear this sites tech section is nothing like it used to be.

honestly im out of ideas on this one man.
did you check for other leaks?
clean the t body although im sure thats not it its easy to do and it cant hurt
im shooting in the dark man without being there when it does it.

did you let the car relearn the idle after cleaning the iacv? and just because you cleaned it doesn't necessarily mean that it's working properly.

yeah I didn't touch anything and let the car idle for five minutes, turned it off, and then started it again. And I talked to a mechanic friend of mine earlier today and he said to unplug the IACV sensor when the car's running and if it doesn't do anything to the idle that the valve is likely bad, and if it does then it's probably fine. Short of replacing the IACV all together I'm not sure how to completely rule it out.
