I've got a 5spd '89 with a 3S-FE that loses power when it warms up.
When driving it while cold, it runs great. Once it warms up though, it turns into a slug. I can barely get it up hills on highways with 4 people in the car, and acceleration isn't that great in any situation.
It idles perfectly while both cold and warm. The temp gauge is always steady when warmed up. I don't know when any of the sensors were last replaced. The flex pipe is broken, but I don't think that affects performance only when it's warm.
The reason I'm bringing this up now is that the timing belt is overdue, and I'm considering putting a different engine in, as I want something reliable for long trips. However, if it turns out to be a simple fix and the compression is ok, I may change the head+oil pump and keep this engine.
It has bad pinging when accelerating between 2000-2300 rpm, or going up a steep hill at less than 2600-2700 rpm. Could this be part of the problem? I suspect it's from the old belt or misadjusted valves.
Another thing is that when I try to start it while warm, it sometimes seems as if the starter is working against the firing cylinders. After it does this for a few seconds, I can let go of the starter, and it will sputter into life from *very* low RPMs, or just die out. Other times it just starts perfectly after 2-3 turns.
Any suggestions?
