Hi Bob/Ken,
Thanks for your reply. I wanted to tell you when this really happened and what was done.
Last week Sunday I purchased a can of Carburetor cleaner. Then I undid one vacuum hose at a time leading to the intake manifold and sprayed a bit of it into the intake. (I have done this in the past and the engine seemed to run real good).
But this time I did something real stupid. I thought I could spray a little into the vacuum tubes this way they would clear up. That's when all this started to happen.
To resolve the problem: I undid one vacuum tube one at a time whilst the engine was running and let it run a bit so any liquid would evaporate. This seemed to resolve the problem.
Last Thursday the car was running fine but was very low on gas (Near empty), so I filled up some gas and parked my car immediately. The next morning when I started it, it began running real rough and it has been ever since.
I hope this might give you a better understanding in the situation of my car problem. May be you may understand what really went wrong.
Hope you can really help.
Thanks very much,
Gerrard Misquita

I took your advise yesterday and yes the car started running smooth after cleaning the spark plugs but in about 10 minutes is was back to normal (Very Rough engine).
This morning I took my car to Toyota and they investigated the case and they say it is the VSV valve that needs replacement (it will cost $600 CDN). Do you think this is really what the problem is?
And the best part is they say they will see if it solves the problem. (Is this a trial and error fix?)
I do not know why they could not just clean the valve and try it. Today there are all sorts of solvents that can clean almost anything.
