DC5 pulling down 1500rpm to 3000rpm

Messages

Hello.

Been in and around the forum for years with ep2, ep3 and eventually getting a dc5 however has developed a little issue that is getting on my nerves.

The car seems to completely bog down between 1500rpm and 3000rpm then it picks up and goes back to normal. Vtec does engage etc so isn't in limp mode and checked for fault codes but nothing stored. I had a search on numerous forums and a lot of people pointing in the direction of the primary o2 sensor. I've since changed this and still the issue occurs.

If I leave it in 4th gear above 3000rpm for a bit, it will act normal for a bit but then revert back to normal below 3000rpm which the only thing I could assume maybe is the cat clogged or the iacv is sticking?

Any help or recommendations is appreciated.
