I have a 1995 Civic Ferio IMPORT, 1.5 16V VTEC.

Just recently it has started to have a drop in acceleration, but only usually between 5000 - 6000 rpm. Sometimes it does in twice in the same gear, between different revs. I thought it might have been dirty injectors, but i tried cleaner and it hasn't really affected it.

I dont think it is the accelerator cable necessarily, but also have no idea what else it could be....

Any suggestions?

Thanks
Matt
