So I'm helping a friend of a friend trouble shoot an engine problem on a 91 4runner with a 22re. It seems the previous owner powerwashed the engine bay just before putting it up for sale, which may or may not have something to do with the problem: The engine is slow getting up to speed and at about 4000 rpm falls flat on its face. TPS seems to check out, though not difinitively, the AFM is sealed, Cat converter is OK, and no apparent vacuum leaks. Got any suggestions?

you might check to see if the valves need to be adjusted. i just had the same problem, and adjusted mine and its a lot better. just make sure you adjust them hot.

Body Damage is Cool

A power washed engine that runs like this makes me immediately suspect water in the distributor.

Pop the distributor cap and spray in down with WD-40. I do not think that is the problem but it will not hurt to try.

Was the problem there from the getgo when purchased or did it start afterwards. My reason being is that if the powerwash is the problem it would have been there from the minute the truck was purchased. If the problem developed afterwards I'd say there is something else wrong. I'm also leaning towards valve lash adjustment. Maybe a fuel problem as well (starving).Any difference if engine is hot or cold.
