Check your charcoal canister and related parts...that's supposed to relieve the pressure to keep HC (hydro carbons) from escaping in the atmosphere...when you fill your tank...those waves in the air spilling out are hydocarbons.

If you have massive pressure that mean either...it got really hot while your car was just sitting there...or your purge canister isn't working.

Man that cap might cause an engine code...your tank isn't supposed to "breath" like that. It's supposed to be completly inclosed and sealed. Emissions stuff rules.

the canister is under the hood. It's not in the tank. But since your idle is so low I'de check the voltage and res. of that sensor.

Do the 240's have an adustable idle screw...my accord has a screw on the intake manifold that you can use to adust the idle...but still...check that sensor.

I just drove a 91 ka24de 240 (mine is a ka24e).

It did the same thing...minus the low idle.

I drove it around and then turned into a parking lot to turn around, right when I was gonna go it didn't...cause it died.

Every time I came to a stop it would die.

Also, compared to my Accord...and my sohc 240, this de felt gutless and weak. I got it up to 4-5k and it still didn't feel right.

I guessed timing or something. I was test driving it and opted out of buying this one. Really nice and clean other than that, but I wanted a good runner, but mostly just wanted to drive a de.

Any way check timing, check the canister, BEFORE you replace stuff CHECK them, check the IAV. I'm just throwing crap out there

By check I mean mechanical and electrical...being resistance and correct voltage at specified operation. I'll look and see if I can find info on ALLDATA (program here at college that has a lot of info for car, make, model, and year) and post those...uh...actually I'll search to make sure they aren't already posted
