Title: URGENT!!!
Post by: Anonymous on October 16, 2005, 14:29
hi guys, was just out driving when i felt a little kick/a little push foward, then noticed my malfunctioning light was on flashing. pulled over and it is now permanently on, tried restarting car and its on all the time.  and when sitting idling it is shuddering a bit like the car could cut out?whats the cause cause,  could it be pre-cats?

it was flashing but no always on, here it is

thats yiour engine check light, MIL, CEL what ever yu want to call it.

First thing you need o do is pop along to yur dealer and have teh read teh code.

don't let thm charge yu it will take all of 30 seconds.

when yu kow what teh code is we can go from there.

ok thanks bud.  so there is no certain thing?  ill let you guys know once i get the code

Is it safe to drive?
Title:
Post by: markiii on October 16, 2005, 16:08
probably, it depends on what the CEL is for.

make sure your oil level is ok first and then take it very easy and yu shudl be ok.

Post by: markiii on October 16, 2005, 18:10

the so called reader in teh car, is only of any use for showing you that there is no oil at all.

by the tie it coes on yr already in troble

you should be checking the dipstick very regulalry

to give you an idea of the possible codes that are read by the OBD-II system Reddi. Now you see why you need to get it read properly

i do check it regularly, only bought car last week so didnt think any need to check it 1 week later.

other thing i forgot to mention is that before i went driving i noticed water coming from my exhauset, shoulnt have been condensation.
Title:
Post by: kanujunkie on October 16, 2005, 19:00
water or coolant??

you'll get a small amount of water from the cat, all modern cars do and after shutdown it may pool, but you need to check wether its coolant. Coolant is normally coloured and has a slightly sweet taste to it, i wouldn't recomend drinking it though

 s:D :D s:D    i have a laptop that can read the fault codes via the on board diagnostic socket   if any one needs to have a fault read and they are near sevenoaks i could pop round..  dealers charge about £75 for this service which takes about 2 minutes.    or ring your breakdown provider, the RAC and the AA will read the code for free and tow it to the garage if its unsafe to drive.. possible cat damage can occur if even a slight misfire goes unchecked

could be a number of things . i had the exact same thing happen to me one rainy sunday afternoon in St Andrews.  Car would turn over but would keep chuggering and thought it was gonna stall.

Sad news is, it was my ECU had packed in and also one of my injectors... just shy of £1k to fix   s:cry: :cry: s:cry:

to give you all an update.  they tested the car an no code showed up so they reset it and now the lights off and doesnt seem to be any problem.  could this light have came on if my rear window wire got tugged to far as forgot it was still in when tried lifting up hard top

Sounds dodgy to me - if the light is on then you have a CEL - and a code with it. Pulling the demister wire will do nothing more than break the wire - it has no connection to the ECU at all. Were you there when they 'read' the code?
Title:
Post by: Anonymous on October 20, 2005, 17:42
no i wasnt there.  the car was being left with them to have the ariel motor replaced aswell so i had to drop it off on way to work and collected when finished

now youve made me sad  s:-( :-( s:-(  was happy thinking there was nothing wrong and just an error that the light came on.

You rekon i should take it to another dealership and have them check?will they do it if light not on?
Title:
Post by: Anonymous on October 20, 2005, 20:18
so should i be worried that they say no code or happy that there doesnt seem to be anything wrong?>

Post by: kanujunkie on October 20, 2005, 20:20
may have just been a glitch, did you say you had the pre-cats in or not?
have you cleaned the MAF sensor at all yet??
Title:
Post by: Anonymous on October 20, 2005, 20:36
they rekond it was just a glitch.

still got pre-cats in jsut now,  nah only had car just under 2 weeks so aint cleaned or checked anything like that yet

i see here  -   m http://www.mr2roc.org/phpBB2/viewtopic. ... maf+sensor (http://www.mr2roc.org/phpBB2/viewtopic.php?t=8453&highlight=maf+sensor) m   that cleaning the MAF can be a good idea so ill do this over the weekend.  i see i need carb cleaner, i pressume i can get this from somewhere like halfrods.  

what do i actually use to clean the 2 wires? some type of brush or jsut spray on the carb cleaner
Title:
Post by: kanujunkie on October 20, 2005, 20:47
dont touch the wires, just spray them, i dont know wether Halfrauds do carb cleaner, i use a product from our stores at work, so cant comment  s:wink: :wink: s:wink:
Title:
Post by: Anonymous on October 20, 2005, 20:49
ok ill get the spray somewhere  and ill just spray it in an nothing else and hopefully this is all the prob was

although you think they would have mentioned it but then why would they if they can get away without saying anything, i hate dealerships  GGGGRRRRRRR,  thank god for this site
Title:
Post by: kanujunkie on October 20, 2005, 20:55
give them they're due this is only a guess and may not be the cause, but cleaning the MAF sensor once in a while is a good idea as it does get a bit coked up and cleaning it can only help, just be careful as the sensor is very delicate and will break if banged or dropped
Title:
Post by: Anonymous on October 20, 2005, 20:57
yeah i suppose, should jsut be happy light not on anymore (hope they didnt just disconnect it,  LOL )

ok will do, cheers buddy!
Title:
Post by: SimonC_Here on October 21, 2005, 08:32
Oh, and take the rubber ring off the sensor as well. Or just don't get any card cleaner on it it might damage the rubber. Halfords do cans of Wynnes (big blue can) which works fine.

If you mean the MAF then no.. petrol goes nowhere near it  s;) ;) s;)  (It's right at the start of the inlet tract, just behind the air filter)

If your petrol goes all over your MAF then something is very, very wrong  s:D :D s:D

Technically that depends if the misfire is down to spark or injector.. Unburnt fuel (misfire due to spark) can kill a CAT quicker than you'd imagine. On an NA car, a misfire due to injector (no fuel hitting the cylinder) isn't so bad. (On a turbo car you'd run a much higher risk of running horribly lean if it wasn't a total injector failure and then blowing a hole in the piston/rings due to detonation).

Personally, I wouldn't want to.. Though having said that, I have in the past.. (misfire due to spark on the Nissan when the crank sensor wires fell off  s:oops: :oops: s:oops:  )

They're fixing this under the "you just bought a secondhand car from us" type warranty, right? If so - hell yes. They're only saying that so they can keep the courtesy car for someone who is paying them pots of cash  s;) ;) s;)

Glad you're back & sorted.
So was it a plug/coil prob rather than injector circuit malfunction?
Title:
Post by: Anonymous on October 26, 2005, 12:51
they just gave me the fault code which i gave about and sais the injector in cilender 4 was faulty and became clogged.  so they replaced it and now seems to be ok.  hopefully i can actually go a week without being back in
