I have a 1994 l reg Corsa GSi, it runs fine but i have a slight flat spot on gear changes. It last roughly about a second but it is on every gear.
Could it be the injectors. Any information will be great as its pi****g me off when i overtake as it lags

Cheers

nope no k&n here, I did have and it did make the flat spots worse so I took it off again.
Car has had a major service from vaux and is no different... no fault codes either.
