No more than 1/3 throtle or it acts like its hitting a rev limiter replaced can sensor and still throws code spent all day at the shop and can't figure it out. Even put in a new pcm my friend thinks its a main harness but that's not cheep any ideas. Need help asap

What are the code numbers you are getting? Have you checked fuel pressure? What type of scanner are you using? One bad injector can make this engine not drivable.
