Hi guys, ive added it to this forum now...
Ive just bought my L reg Corsa Gsi, and i think it may be a bit boogard?
Basically after taking it on the motorway for about half hour i slowed down to 30 through the streets to go home, when the car, can only be described as chugging?
It still drives....just about. hardly any power, and the noise is terrible, it kinda goes (from the exhaust) dumdumdededumdumdumdedumdedum and visually i can see the exhaust pouting with each dum or de????!!
i thought that maybe the fuel pump had gone and that not enough fuel was going through? although i spoke to a friend who says its ssounds like its not firing on all cylinders??
Please help!!!!!

no lights or temp increase?
def not just cold start - something is wrong
ICV/AFM? is this easy/cheap to repair?
also damn this site is quick! must be loads of peeps on here!!!
ok now thats in here from other post won't have any repeats....
its done a lot of miles, sounds like one of ure sensors has probably gone and with it being a vx most likely AFM or ICV....
sounds more like AFM with it running chuggy .etc if it was ICV the revs shud be moving quite a bit up nd down when u start....
have you checked ure spark plugs are all in good condition to mate?
AFM is around 200 new but dont worry they go on eBay for a more resonable 60-80 odd quid just make sure its the right one for yours
ICV is a bit harder to come by on eBay... they go for about 40 notes

sounds like your AFM/AMM to me.... someone else might be able to confirm this but from the chugging and lumpy'ness i wud reckon its that.....
jus let some other ppl have a say and see what they think

given its an L reg GSi, its most probably a C16 unless the engine has once been swopped...

Check the basics first, fuel, ignition, compression, if they're ok thats a good start. To check the sensors, run the engine and disconnect them one at a time, if the sensor is faulty then it'll make no difference when you disconnect it, if the sensors fine it should start to run even worse...

what do i say! it now light enough for me to have a poke about...
started it and sure enough still the same so i took the head cover off to find in dredful condition the spark leads! they are magnacor leads but loads of the silicon has come off?!? i put some electrical tape round the open wire and the car seems to be ok again?!? - i will need to buy some new leads - think some standards to be honest!?!
thankyou all though for putting in your view!
