car struggling

[DNTBLO_S2k]

hey everyone just wondering if anyone can help me out. when driving my car seems to struggle sometime at low revs usually in first or second gear. its like i put my foot down but its dying and about to stall but dosnt it just hopps. its while driving not taking off and only happens sometimes. just gets real anoying have to press then clutch in and back out then it goes away.

[Zilli]

what revs are we tlaking about here? dont forget our cars are torqueless... so at low revs its going to be hard to say the least... most manual cars at very low revs in any gear will sputter or hop around... you just have to clutch in and get a lower gear, or re-launch...

juding by your avatar, youve made a mess of your gear ratio's too... and thats not going to help

[.::F[L]Y::.]

feels like its bogging?

[Vuey]

is it like "bunny hopping" when your taking off ? the revs drop and the car just hops uncontrollably ?

[.::F[L]Y::.]

^^ i think his talking about that....

happend to me in my previous S. any idea what it is Vuey? my guess is it could be map sensor?

[DNTBLO_S2k]

yeh vuey and fly thats it spot on man dont know why it dose it, the rev drop buy em self, nuthing to do with bad taking of it happens after taking off

and how do you thing ive done that ay?

[JamB]

ur rims are huge i think thats wat he means

It's the map sensor but even if you replace it (about $400+) it might still happen when the car is hot.

It happened to me a lot when the car was hot and in traffic. I have an Injen intake and assume the hesitation was an effect of heat soak. The only way to clear the heat soak was to rev and get cooler air into the intake.

Do a search on S2Ki forums for "hesitation" and you'll find many results. Also search for MAP WHACK where people whack the map sensor and all is well again. Even jiggling the wires around the map sensor can help.

I had exactly the same issue a while back. i did everything as above. it sorted itself out for a while. But the problem occasionally re-occurs. i haven’t replaced the map sensor yet. but let us know the results if you end up replacing it.

i had a trust pod filter and for some reason when i put the OEM one back in, the revs seemed abit more stable in the heat. I cant guarantee it will work for you though, as a friend just suggested to just give it a try.

Hope this helps.

your pretty much spot on Justin :thumbsup:

i hear its a common problem on 99-01's. Use to happen to my 99 .

they (s2ki - under the hood section) suggest you give it a firm whack ( but not too hard )with the handle of a screw driver a dozen times or so .It didnt completely stop the problem , but seemed to help and it happened less frequet after i gave it a few whacks .

see the highlighted area in the pic of where the map sensor is located.

[aznsiko]

i have this problem too when im in traffic.. doesnt happen often so i never cared much.. but yes.. apparently the MAP WHACK suppose to help..

[IEVAQ8]

common prob, it happens to me in my dc2r, only once war and in traffic or really hot........and i also noticed it only started hapening when i installed and tunned my stainless steel headers and vafc 2, hope i have helped

[DNTBLO_S2k]

yeh it happens heaps in traffic but just here and then, ill try tapping the sensor thig see if it helps. thanks allot for the help everyone

[Zilli]

and how do you thing ive done that ay?

im not having a go at you bro, the car looks hot, but the huge rims throw out your gear ratio's, not to mention the extra straint in CV's, clutch, gearbox and evenutally your motor

[DNTBLO_S2k]

yeh all good mate weve put bigger wheels on better cars anything you put on a car will tend to wreck something else. problems were there before the wheels anyway.
we have a s15 with 22inch wheels no probs there and its putting out a lot of power mate.
thanks for the help everyone.
im gonna go wack my sensor see if it helps

[NVD52K]

ive had this happen to me although only in hot weather it feels sluggish like the car is struggling to go

[CRXONE]

I swear its the 19's! Takes more revs to move bigger wheels

or are they 20's?

[justinfox]

Everyone suggesting it's the wheels should stop right there as hesitation in 1st/2nd gear on an S2000 has got NOTHING to do with the wheels at all.

[WhiteAP1]

Its like when your old nintendo cardtridges didnt work, pick it up, blow the dust out and then it worked. The connections just effected by grime build up. Disconnect it, give it a friendly tap and off you go.

[NVD52K]

i was wandering if there was another way which would help for a longer time rather then the tapping the sensor could cleaning the throttle body changing spark plugs have anything of any difference in it? tried the map wack doesnt really work for my car just feels like my car accelerates and brakes

[Andw0o]

Prehaps a new map sensor.

[Andw0o]

mind u thats about 400+

[NVD52K]

where can i order it in from?

[WhiteAP1]

Honda

[NVD52K]

today i unscrewed the map sensor and sprayed throttle body cleaner in and dried it down with a compressor done a good job works good again

[DNTBLO_S2k]

there 20's mate and it happend before i put the wheels on its got nothing to do with the wheels

[amirul]

yea mine got 20" too, but no problem...........

[DNTBLO_S2k]

yea mine got 20" too, but no problem...........

20's are sex haha

[BLE5SD_S2K]

same....i got 20's but mine is fine......

it happened to me when i put the K&N induction......... but then i put the standard cover over the K&N filter and it hasnt happened since...

[integrity]

open box just sounds good but if anything is a power loss and allows more heat soak.

20's dont have much to do with it but consider the weight of each "chromie" as opposed to OEM or lightweight wheels and think how much harder the "S" has to work to get a rotation on them (not dramatically much but it still isnt the best to have chromies with open box on a hot day)

[DNTBLO_S2k]

yeh mite put my airbox back on louey is it running better?

[ECU-MAN]

you guys should try and reset the ECU, It will run well for a while but adventually the problem will reapear again.

I just keep resetting the ECU when ever it comes back.

[luder]

It's because your a bling fanatic /end jokes :)

[BLE5SD_S2K]

yeh i know the 20's strain the F*** out of the car......ive had to change my wheel bearings twice already:(

but yeh everyone has a differnt taste in wheels.....

and yeh it did go away as soon as i put the airbox back on the K&N filter....:thumbsup:

[NVD52K]

after u change spark plugs clean the throttle body and sensor has a big difference most probrably use ngk platinum spark plugs cost more but u can feel a big difference

[.::F[L]Y::.]

how does the car feel with 20's? im guessing would feel heaps slow? since there is a bigger rolling diameter?

i remember test driving an s15 with 20" chromes ages ago and it was real slow!

[preludacris]

20 inch chrome on a 2 litre engine, im guessing would be slower than a civic.. lol.

[DNTBLO_S2k]

nah mate not that slow u just gotta give it more, its slow without hitting vtec but ive beaten a s15, r33 and a xr8 with 20's on my car so im not complaining.
hey berman sexspec yo u know you wanna slam it on 20's
air box on louie i cant feel a difference

[BLE5SD_S2K]

yeh tru.....with the 20's the car is just a bit slow on acceleration....but once rolling it feels the same as when i had the OEM wheels on it......ive beaten SS commodores and rexys with my 20's on......:honda::thumbsup::honda:


but yeh bro, i dunno wats wrong with ur car sunny but with my airbox on, the S2 runs heaps smoother......maybe u need to change ur filter??

is your car modded?

and also were these cars that you beat modified?

im not doubting you...but its sorta hard to believe a stock s2k with huge 20" chromes can beat an XR8. unless the xr8 was rolling on 22's or something lol

[DNTBLO_S2k]

stock xr8, skyline had a few mods but died keeping up in top end.
man ive seen so many quick s15 with 22's and 20s on it really dont make much of i difference when u pushthe hell out of your car

yes its believable to see an s15 on 20s or 22's run quick times cause they have more than 220KW at the rear wheels to get the car moving. An s2000 however only has about 125KW-135KW at the wheels stock. Also add the fact that its gutless below 4500RPM....I remember one yr watching the MC racing s2000 getting dynoed at autosalon had i think 20" chromes. only pulled 110Kw atw due to the sheer size of the wheels.

personally i wouldnt put wheels of that size on my s2 but chrome does sorta go well with the car. ;)

[Zilli]

whilst the wheel problem may not be associated with the OP's issue i have to agree with Fly... the wheels do look hot on the car, but yeh you will lose a LOT of response and pickup. Essentially you are putting the equivalent of a higher final drive in your car...

[NVD52K]

i cleaned out my throttle body with spray and bought new spark plugs and cleaned out the map sensor aswell and let it to dry make sure u clean the throttle body first and drive it around then change the spark plugs after since your putting new ones im using ngk platinum atm $70 for about 4 throttle body cleaner about $7.95

wait couple of months and see the mc racing s2k, queen st racing have just redone it and put a 20b in it.

wow twice already...........gotta take it easy bro.

told u not to drift that much with 20" lol hahahah:p

[integrity]

each to their own i guess,

but looks dont cater for reliability in my world.

i used to have 20"s myself, worst mistake imo

when i put my lightweight 18's n i felt like i made a extra 50kw ATW.

kinda suprises me how your 20"s on your stock S beat a XR8, rexies and so on ...

you should dyno it

[NVD52K]

i seen on you tube a s2000 with soarer engine in it very beasty and powerful 1 j engine !!!

[WhiteAP1]

Yeah the supra swaps been around for a while, you should check out the LS1 conversions, lighter and more powerful engine.
