My 93 toyota 4runner (2.4 Diesel Turbo) is experiencing power-loss, the engine revs really high but the truck's not going fast enough. Whats wrong? I usually experience this while going up a hill. Its not really that weak but it takes time to pick up speed. I could hardly go up a steep hill in 3rd gear, I'd always have to bring it back down to 2nd or 1st gear to get to the top. The engine sounds very powerful and the mechanic thats been working on it says he just cant figure out what the problem is and suggested it could be a problem deep inside the engine (pistons, cylinder-head or block) but we've had all those replaced so he just became absolutely clueless. I still use the 4runner everyday and everything seems to be OK except for the weakness! But it does consume more fuel than it used to. The most annoying thing is that the engine sounds almost brand new and powerful but all that power is just not getting to the wheels I guess. Please reply and suggest something. By the way this is coming to you guys all the way from the Solomon Islands in the South Pacific!
