My mates Corsa stutters under accleration when the engine is under load - ie going up a hill - it will accelerate then stay at a certain rpm for a split second before carrying on - especially when cold. Feels like the driver keeps taking his foot off the accelerator then putting it back on.
Any ideas?
Thanks
Assuming it is petrol then first thing to check might be spark plugs.

Yea - thats what I thought and he's gonna change them asap.
Any other possibilites though once thats been checked?
Plugs or leads. Probably the later- replace the heatshields (if this is the old family 2 8 valver) too. Use genuine GM.

No, 16v
Still Ht leads and make sure the coil pack surface is clean. If its suffering from a poor idle as well, then look at the EGR valve which fail about as often as the pope preys...
