car falling on its face

[hayabusa1285]

so today i was getting on the high way and i took 1st to bout 7k and shifted 2nd once in 2nd car felt like it just fell on its face, like i had lost power. i gave it a lil gas and it went. my first thought were i wasn't giving it enough gas to keep it reving at those engine speed but went throught the rest of the gear just fine. next thing i notice i am getting off the high way (it's been raining all day) so i got on it a lil bit but at bout 6 it did it again just kinda felt like it fell on its face. but than getting to the next light i reved out first too 7 and vtech did hit. i didn't run it any higher and kept it in the lower revs. i check to make sure oil was in it. there was oil now as far as the level i dont know i am waiting till it cools down a lil before i check again.

now just to give you an idea of the day we are having its bout 74F really raining day. mods i have are a Fujita CAI, header and no cat and it is a MY00

any thought?

A bunch of questions.

Is your carpet bunched up under the gas pedal? That can make it difficult to fully depress the pedal from time to time.
Did you park it in the pouring rain for any length of time? Did you plug the rain gutter hole under the hood lip? Do you have an "umbrella" over the filter? If rain got into the filter while parked, you may be sucking up a bit of water into the engine but not enough to lock it.
Is the air filter clogged or dirty?
When was the last time you checked the sparkplugs for condition and gap?
When you know what the oil level really is, report back. Low oil will cause VTEC problems.
Have you tried the MAP thing? Disconnect, reconnect the harness and secure it with a zip tie.
Do you have a CEL?

Can you go back and edit your post for punctuation and spelling so it's a bit easier to read? :laugh:

Pedal felt fine no trouple there but ill check that as well.
Parked in the rain? Over a day no. now for as when it started raining i am not for sure but i parked it bout 12 am last night n it wasnt raining. My guess on how long it sat in the rain is over 5 hours.
as to the gutter hole i am not for sure as to what you mean. now i did replace the stock hood with a VIS carbon fiber one. The filter wasnt dirty when i installed it on the car i have put about 3K on it since install. as for clogged i dont believe so,the car felt fine the night before running though the first 3 gears(but will check that as well). spark plugs were replaced bout 10K ago gap and everything.
oil...still waiting.
MAP no i havnt tried that but i think i will.
no CEL.


What you were saying bout sucking water up but not enough to lock it. sounds bout how it was acting. it didnt feel like the computer was stoping the car just that the car wasnt getting enough of something to contuine.

oh and i fixxed my 1st post still a lil sleepy :laugh:

How long had you been driving the car prior to trying to rev it that high? Was the car fully up to operating temperature? If not, the car will not allow VTEC to engage.

[hayabusa1285]

it was fully warmed up. i had already driven 7 miles

This is the gutter hole I'm talking about:

It doesn't matter what kind of hood you have. Rain that falls on the front of the car can use that side gutter to drain away. When it reaches that hole, it goes down and right on top of the Fujita air filter, which is mount in that empty space behind the fake air duct in the bumper. If the filter gets completely water logged, the water will then begin to flow into the first elbow of the intake tube. That elbow is pointed up very slightly and it can hold as much as 100 cc of water. You only need to leave it out in heavy rain for about an hour for it to accumulate enough water in that elbow to cause a problem. That's why people with those kinds of CAIs plug that hole and make an umbrella for the filter. Depending on how much water was actually in the elbow and how much vacuum there was when you started the engine, it has been known to hydrolock the motor. However, if only a little bit of water gets into the intake manifold, then you can have sputtering problems till the water has been dried up. It might be a good idea to get to the filter and take it out and see how wet it is and if there is any signs that water got into the elbow. If there is wetness in the elbow, you may have your answer. Driving in heavy rain with this type of CAI isn't the problem as the engine can deal with small bits of water as it runs. However parking in heavy rain is the most dangerous thing one can do in an S2000 when it has the Fujita/Injen/AEM type of intake because it give the water time to collect. Low rpm running isn't enough vacuum to suck up water in gobs. It's when the rpm is elevated that there is sufficient vacuum to pull globs of water up the pipe.
You should still do the MAP thing.

ok thanks Repiv this sound excatly what the car was doing. so i guess ill go about plugging the hole and checking on the filter. now as far as driving i still have to drive bout 30 miles to home so i can take it apart. u think driving in lower rpm (no more than 4K) would be alright for the car is should i do the surgery in the parking lot?

Hey Dave should go to S2000.com and try reading some of Java's posts

Unless it's been parked out in the rain again, what water that there may have been in there is mostly so diminished that it won't do anymore harm. Just drive it sedately. If it has been sitting out in the rain, it would be wise to not drive it till you check the elbow and filter.

[hayabusa1285]

well i made it home the elbow didnt have any water in it i guess it all diminished. what i did was stick the a vaccum in the intake pushed it all the too the filter and plugged the open end and let it pull air(and water) through the vaccum and did pull out some water i did plug up that drain and sealed it. im about to go driving to get some food ill let u know it acts than

:) car is running good again thanks repiv for all ur help again:thumbup:
