Hi Ferdi's the name

I recently bought a 1993 ES300. I have had the engine replaced and when the vehicle came back, the performance was worse than ever. The problem ends up being the vacuum pipes that was fitted back wrong. The diagram in the hood shows two connections running to a T V V unit. The problem is that I don't see such a unit anywhere. Can any one assist me in where to locate these units? (By the way what does T V V stand for.)

i have a diagram of all the parts for the 92-96 ES. If i get a chance i will try and see but i cannot draw the diagrams, i will have to scan them, so i will have to buy a scanner first... might take about a week. i will let you know what happens

 

actually on an 1mz-fe engine the tvv is above the engine oil filler tank. the tvv unit is part of the emissions system and if i am correct, eventually leads to the charcoal canister. how did u know the vacuum pipes were fitted back wrong? (what do u mean by wrong ) then maybe i can help u more.
sorry for the delay
