I have a 2000 Vauxhall Corsa 1.0 12V Club on the B shape. I have just had the timing chain and tensioners etc replced because i was told that was the cause of a rattling noise. I also have a noise that i beleive is pinking, which has been happening for about a year probably now. I does it more when the engine is cold and only when pushed hard but NOT ON HIGH REVS, only between 2500 - 4500rpm ish, sometimes if i put my foot not quite right down, it'l do it, then if i put it to the floor it;l stop.
Also, when i do that, there seems to be like a pause before i get the power if you know what i mean, like a dead spot.
Another problem is, only when the engine is cold too, if i'm in say 2nd gear about 3000rpm, and speed up foot to floor, it'l pick up a bit sluggishly, then all of a sudden usually quite high rpm it will go like a turbo has kicked in, about 5500-6000rpm. I don't know if all these problems are connected but i'm going to a garage to check it on computer tomorrow, and then if that doesn't show anything, i mught put it on a dyno, to get the figures max hp @? for example, then see if anything IS wrong with it, peaky hp etc.
Any help much appreciated.
I'm new, so if you need any other info, please ask!
Thanks
