Power cuts when cruising under a light throttle
Now that my OCV issues are a thing of the past (or is it my OCD?) my '98 GS300 seems to exhibit a different problem.
When cruising at speed, say 60 mph along the motorway (freeway) under a light throttle to maintain, the engine suddenly loses power, as if the throttle has closed. No warning lights, no misfires and pressing the accelerator further seems to clear the problem.
The engine starts well and fuel consumption is good. This does not seem to happen in traffic but only at speed under a light throttle. This is very random and occasional.
Has anyone experienced this and can suggest a fix?

I would clean out your MAF sensor and clean out your throttle body. My guess is that they are both filthy. Also, make sure your air filter is clean too. If the air filter is dirty, the MAF sensor could be reading incorrectly and relaying incorrect data to the body butterfly valve (ECM). Get a can of MAF sensor cleaner, and Brake cleaner for the throttle body, $15 bucks max for both. Then move on to other more expensive/time consuming items.
