lost of power at full throttle??
 
I have a mk2 with 7mge swap. Everything is good. The only problem I’m having is At full throttle it would loose power. Like the car is shut off. Then when I let go of the throttle and give it half throttle everything is good. It runs fine until I full throttle it. And the other thing is. Between 2 and 3 thousand rpm. It would bog out. When it goes pass 3k. It would run fine. It’s the same in every gear. I tried Putting 2 other tps on it. Still the same. If you know what the problem is hit me up... thanks..

maybe you got water in the spark plug holes i would missfire and lose power when i had that when i would almost reach 4-5k but i got a 7mgte might be different but i replaced mine and havent had a problem ever since or oyu might have a vacuum line unhooked or a leak check all your connection and compare to the tsrm to see if theyre the same

that is true but you would notice it when the cars at an idle and you wouldnt really get any power id say get a chiltons and jump your system and see what the code reads out to be if it tells you its the air intake temperature signal then you may just need to change the spark plugs. and "IF" you do have water in the plug holes then when you change the plugs spray some ether down in the holes so that it will start right up.

Some misfires don't show up at idle and only occur under heavy loads. I would check plugs/wires first. You can load the engine and mist water on the wires with a spray bottle and listen for arching to check the condition of the wires.

for sure i know its not the plugs. i put in 2 sets. i switch the plug wires. and it still act up. the only thing that is left to do is put a new fuelpump. i did a fuelpressure test. and the pressure is weak. thats what you get when you do a hybrid motor swap..
