problem with the toyota rav4?

[In The Rat Race]

Toyota Rav4 2.0L Auto 5 door x reg 2000
To keep it short, when I bought the car the head gasket had gone and it had been driven whilst the engine was sucking in lots of water (radiator coolant). Now I've had the head gasket replaced, but the engine lacks power (as it did before replacement of head gasket), excellerates well to begin with but once you get to a high rev or under any load(up hill) there is lack of pulling power. The engine revs really well, right up to where it should, when you step down on the accelerator it drops a gear fine and revs up well but just no pulling power. It has been suggested that as coolant was going through the combustion chambre and ultimately out the exhaust (and there were lots of it) then the lack of power maybe due to water damage in the exhaust and becoming almost blocked. Could also be the auto box slipping? She revs well, she wants to go but she don't. Any ideas please?

If you are getting no engine fault codes then i would guess that the engine is meant to perform like this or is worn out.

I think you have internal engine problems.Try some fuel injector cleaner

could have had coolant in your exhaust, sounds like maybe a clogged cat or o2 sensor going bad, is their a check engine light?
