Hello all...I searched for miles and couldnt find anything helpful in the archives and I was hoping someone could help me out by giving me some direction if anything. Problem(s) im having is that my engine(ka24e) is bogging right around the 2500 rpm limit and its doing this in every single gear (5 speed). I just bought the car bout 3 weeks ago or so and it just started doing this about 10 days ago. I replaced the following in an attempt to remedy

lugs -wires- cap- rotor- fuel filter- oil/filter- o2 sensor- valve cover gasket- and finally cat converter. I also had timing reset and im STILL having the same problem- thought it could be the valves or some form of exhast back pressure but im doubting now. I am this close to taking it to the dealership (which i utterly hate) but it seems like i have no choice. Any helpful ideas - suggestions - questions would be deeply appreciated. Thanks
