Hi all, I have a corsa b 1.4 96 and it has a flat spot between 1800 and 2100 rpm. It seems to be worst when the engine is warm.
There is no smoke fromthe exhaust and the engine management light is not on.
I have read lots on forums about a similar problems but no one reports if they fixed it.
Would love some advice on this.

Regards and thanks in advance.
Mike

When was it last fully serviced?

If it's worse when warm chances are it's a fuel/air issue rather than ignition. Around that time they did the 1.4 in both 8v and 16v versions - which is yours?

Have you reccently added anything? Such as air filter? Etc?

I know that heat soak is a common flat spot cause
