ok i have a 93 sc300 w/ a 1jzgte twin turbo. the car will start right up, idle good, but when i go to drive it, it will do ok but if i stomp on it, it will just brake all up and have no power if i let off the gas some it will go but not fast. and now the car is getting hot. the boost gauge will only go up to vac 3. the car was putting out black smoke so i put new ngks plugs and coils (coils are used). now no smoke but car still brakes up (like a rev limiter) it cant be a head gasket bc the oil is still clean. and car will fire right upand i can here the fule pump working. i need help i am lost.

 

comp test says 165 psi in all 6. could the no power be injectors? how do i test them?

 

i have pop a hose just came off. so i put it back on and filled the coolant and drove a mile and pop another.

 

this makes no sense.

 

what part? sorry i will try and tell it better just so damn mad

 

Fuel filter or pump? I would start there.

 

i have a walbro 255 pump

 

so i will try filter

 

i say u probably have the wrong map sensor on it. if it doesn't have a yellow or green label on it, it wont take boost.

 

do you have a pic on where the sensor is
