Alright guys, my car starts up fine on a cold start but when i drive it for the day and shut it off and go to start it again it doesn't start, when it does my rpms are very low and get lower and lower close to 0 then dies.. then starts up fine again then dies.. could it be battery or alternator?

Maybe the idle is too low?

RDAYA0

Man i don't know..help me out guys

fastrc2

as it gets lower does it feel like its misfiring? if so it sounds like a crank position sensor going open circuit. to test it, remove it form the vehicle, and apply an ohmeter, and hit it with a hair dryer, see what the numbers do. if your not sure ost the results, and the rate of change and ill help

RDAYA0

no no just idles really low and tries to stay alive but eventually dies..

pkdog167

Will it die if you give a little gas and stay above 700rpm?

RDAYA0

no it stays on but i have to drive off to keep it on, the first couple of meters driving off it feels like power is cutting off then eventually comes back to normal after driving awhile.

check ur IAC (idle air flow), it could be clogged up, or maybe a combination of the throttle plate and IAC being dirty. To clean ur IAC just take it off and very gently and lightly spay some brake clean on it and gently wipe it off, this may not fix it and may damage it if done incorrectly, but u should see some build up when u remove it, and the throttle plate brake clean and a rag and wipe it. See if this helps. let me know.

I think your idle needs to be adjusted up or you may need to replace your IVAC

how hot does it get where you are?

Wow, I love the answers people give. Before you do anything try driving it to your local pep boys, autozone, etc, and have them test your battery and alternator. If that checks out THEN start looking into the other stuff mentioned.

RDAYA0

Well i live in canada or no pep boys or autozone here, I'll get the battery/alt tested right away because i had to get dropped off to work today due to car not starting just starts and dies right away then it just cranks after a few tries

my car started up good couple weeks ago but i always had a low idle problem, already cleanned

ivac
fitv
throttle body
adjusted idle screw

still get low idle :S

count me out

alternator is either dying, or belt is loose.

once the car is running, the battery doesnt do dick but get recharged. alt runs everything, check it out.

RDAYA0

but what if the battery is dead and doesnt want to recharge? then it still could be battery, ill get em both tested out its the only next step to follow. thanks guys h-t is always helpful

on my dd, d16y8 motor, i just went thru the same problem
is ur cel on? if so, check the sensor on the intake manifold
mine broke and came off, and my car kept dieing and idled close to 0
fixed the swtich, im good to go.
hope it helps!

o2 sensor's on there and intact, hmmm i hope its not the alternator it's a harder fix than a battery...how do u guys take it out ? 94 civic btw..

eg customs

if you want to check if your alternator is bad, turn on the car and disconnect the red wire from the battery and if the car turns off rights away then you alternator is bad

civic2489

try cheking the eld (electric load detector fuse) if it is bad then it will have the same symtems you have may car did this and thats what it was check it out let me know

RDAYA0

just tested the alt out, car started up right away this morning? then i took red cable off and it ran with no hesitation for about 30 seconds then i turned off the car, hmm...seems good now, i just found out that a open wire which is the wire that hooks up my vtec spool valve was touching the metal body of my car inside near the ecu i just put some electrical tape around it...could that woulda been my problem? ill look further more.. thanks

team_exceed

well, i didnt read thru all of this, but did you check the tps sensor?
unhook the tps while it is running, but make sure someone is in the driver seat ready to shut it off. if the tps is bad, it will not change the idle, but if it is good, im pretty sure it will just rev all the way up.

if any damage happens, im not responsible!

i'm thinking it's ur battery, have it recharge or if it's not good, get a new one. mine's doing the same thing, sometimes it'll just idle very low and go back up. sometimes it'll just die and i'll try starting it and it will crank but won't start, i then have to turn off my deck and wait for a while then it'll work again. i'm assuming it's ur battery.

RDAYA0

yeah im getting a new battery tomorrow, a brand new buddyclub one for jdm/usdm cars...hope this helps out..ill get back to this when i get it switched..thanks for the feedback fellow members
