My car will not accelerate more then 15 mph with about roughly 2,000 RPM. Even if I floor it at take off nothing.
I've replaced Cam Shaft Sensor. (Cam Shaft Sensor A - Low input) - Still showing after 2 replacements.
Replaced Transmission Range Sensor. Still nothing.

I am stuck. I don't know where my problem could be coming from. I've already had the Timing belt replaced and looked over by three other mechanics other then me. They cant even find the problem.

This sounds like a wiring issue. Check to make sure the plug for the cam sensor is clean and free of corrosion. Also, check the wiring to the CAM sensor to make sure there are no open circuits or damaged wiring. Work your way back to the PCM checking the wiring. Once to the pcm, check the wire for continuity. Let me know how much resistance is there.
