hi just wondering if someone could help.my corsa 1.2 16v is chugging constantly, ive replaced coil pack,throttle potentiometer,idle valve and the cat.could this be electrical or does the ecu need reset before it works properly again?? help with this would be much appreciated

might be worth getting it on a diagnostic machine see if any faults come up

does it chug like its going to stall kinda?

yeah its does that but when i put the boot down it eventually gets a little power and moves. i had it done a couple of weeks ago and they told me about the throttle potentiometer,so i replaced it but still does the same.

start with the obvous 1st,
sparkplugs ht leads air and fuel filter

if not that the best idea like i said would be diagnostics n see if any errors show
could be a MAF sensor or somthing

yup bought spark plugs,air and fuel filter just cant seem to get anything thats going to stop the car from jumping like a kangaroo lol,had diagnostics done today it only said there was a low voltage but the guy cleared the codes told me to run it over the weekend but dont know what else it could be.

i also got a fuel pump is there some sort of fuel system other than the pump and filter that could be causing this??

blocked fuel line? not sure pal
what wer the errors it came up with?
low voltage to what?

on the air flow meter but the guy said that happens if the ignition is on and you change something it just registers it on the ecu. but he cleared the codes and its been fine.also my eps light stays on for a few seconds when i turn the car on,the car stutters till that light goes off then it seems to idle ok,any suggestions about that?? thanks for this advice friend!!

have u replaced the maf sensor?

if its showing low votlage at maf then id say it was that thats not working
your car shouldnt register any codesif theres nothing wrong with it, so id say the maf

if it wasnt the maf sensor could it be the timing aswel if that is off a little or would the car just not work at all if its off.

well the x12xe was chain not belt which cannot slip
it can go slack but usualy just gets noisy

hi just got the maf sensor checked at vauxhall they said there is nothing wrong with it,he tried getting me to leave the car with them,but defo couldnt they where wanting 45 quid an hour for trying to find out what it was.anymore ideas of what it could be??

only thing else i can think is lambda sensor
afterthat im fresh out of ideas!
sorry buddy!

hi, did u sort ur prob out? my 1.2 16v just died wen u touched the throttle, got the rac out they said it was the fuel relay, changed that(i think thats what i changed anyway,£3.50) and cleaned the throttle body,its bin fine since. did u checked yours?

no i havent been able to fix it but i will give this a try!! thanks ohh where is the relay?? i dont have a clue about relays lol
