need a bit of help rearly ive got a 1 liter 3cylinder corsa as a dayly smoker!
as of last week the idle has gone shit (just refuses 2 idle) and when driving half way though the revs it hesitates (like u have run into a brick wall) then after a second or 2 it clears and ur off again!

so far ive checked the plugs, coil pack, and airmass but all these seem fine??
any idears would be more than welcome

thanks inadvance!

 

Cam sensor, crank sensor or air mass but you've checked that...

 

yer ive checked the airmass and i would have thought if it was the crank or cam sensor it would run crap all the time!

 

i have just wrote in another post above that is what my mrs was doing i put the code reader onto it and it showed the crank sensor was u/s seems to have cleared the fault at the min

 

did clearing the fault stop it hesisating and sort the idle?
as after testing the airmass 2 night i left the battery disconected hoping by the morning it will have cleared the feult memory?

 

do a diag

 

would do but im a vw teck so only have vw diagnostic tools and sadly dont know any vauxhall ppl in croydon!

 

buy a code reader you can get them on ebay for 30-40 quid i think, i fitted the new crank sensor and reset the engine management light and it has been fine since fingers crossed!! in the matter of 3 months iv done this and the co2 sensor as this packed up as well the car has only covered 28k from new

 

yer mine has only doen 51k i think so for its age is quite low!
might try and find some one 2moro with a fault reader unless any1 has any othe idears!

o one more thing how much was the crank sensor?

 

I could pretty much guarantee thats the problem. I sell cars and ifs always one of those three things.....

 

i got one of ebay mate for Ł18 posted next day

 

if you can get to redcar i will have a look for you .im a vauxhall tech

 

when you put your foot down does it pop and fart almost as if the exhaust is blocked?but will rev if you only use light throttle?

 

Check the oil level LOL. When the oil lever gets low in the one i had, it did the same.

 

if its a corsa b (early shape} i would think its the idle stepper motor very commom fault if thats any help.

 

when you put your foot down does it pop and fart almost as if the exhaust is blocked?but will rev if you only use light throttle

yep thats excatly what it does as well as not idle!

 

well my bet is on O2 sensor code being stored!almost certain your mass air flow is fucked

 

nope lol that was my first thought but ive replace the air mass!

 

with a new or second hand one

 

Have you do a paper clip fault test on it?

If not follow the link http://www.topbuzz.co.uk/ and go into the technical section, explains how to do a paper clip test and tells you what the codes mean.

 

new one!

 

Take it from someone who has had 18 vauxhalls, the paper clip test is like god.

 

cheers for the link mate!
if i cant find some 1 2moro with a diagnostic tool 2moro i will give it a go!

no one round the croydon - crawley way have a diagnotic tool and want 2 earn some easy cash?

 

any1?
