After you replaced the O2 sensor and cleared the code did you recheck your codes?

Try checking on the knock sensor and wire to it. That could randomly affect power.

Pull the covers and check your timing belt and the geared pulley. If the belt skipped or the keyway / geared pulley are damaged those can both cause loss of power.

Yes i recheck the codes, none, went for a drive and it came back.

There is no knock sensor on te ej18 from 93->95

The timingbelt ar in place, and everything is correct.


I have run a few test's and i think the fuel pressure regulator is ****'t.
But now it's easter so i cant get hold of one for a few days.

Get a fuel pressure tester if you can. Easy to do.
