Ok, then most likely you have a ignition related problem but its still doesn't hurt to check your fuel pressure across the board. Alot of times its difficult to diagnose based simply on the symptoms as fuel delivery issues and ignition issues can cause the same problems. A weak coil, a bad ignition module, fouled plugs, cracked or fouled wires and so on and so on can all cause you to miss and cause high rpm issues as a stronger spark is necessary up top and under heavy loads on the engine. I would just rule out pressure first then check the status of the spark and then you get to move on to trying to diagnose the injectors. Good luck,
