First thing to try would be different fuel. Use a fuel stabilizer and fill with good gas. see if that helps. Also, check the fuel pressure.

My truck so weak when going up the hill...Nissan 4x4 4 cylinder


start with the basics does it need a new fuel or air filtre you do not mention what type of hill you are trying to climb is it off road on road are you keeping the turbo working ie the turbo will not be effective below a certine rev so if you change gear and the revs fall below the piont were the turbo should kick in then the turbo will not work if all is right with previous could be a poor turbo or a leak in turbo system

actually it is called a lock out torque convertor. when you go into 3rd gear and reach certain conditions it will lock the torque converter making it like a standard shift. so basically it is a 4th gear. this is done for fuel economy.

Power loss and black smoke?


I had a similar issue to this after I got in a VERY small fender bender (literally) in an 87 Turbo Supra. In my case, my pasenger fender got pushed in JUST enough to crack a charge pipe and cause a boost leak.

Basically, what was happening was the turbo would spool and build boost, the mass fair flow sensor would read all this air coming in and tell the ECU to dial up the the appropriate amount of fuel. When the air reached the cracks in the charge pipe, it would escape out of them. Thus there was a much lower air-to-fuel ratio, causing less fuel to combust, which lead to power loss and black smoke out of the exhaust.

My guess is either an oxygen sensor, or more likely a boost leak.

Good luck mate.
