Sounds like a valve problem. check compression running and non-running. valve sealing at higher rpm is usually a valve spring problem is if runs ok at idle.

Under 2000 rpms runs bad/hesitates/check engine light


This IAC valve runs only when your foot is off the gas pedal. Mainly to keep the engine from stalling and keeping it at a safe RPM. If it is running bad under 2000RPM, more than likely its the IAC valve or a vacuum leak. Clean or replace the IAC valve....Hopefully this helps!!

p1545 is a throttle control malfuction code

You can try to reset the throttle body by opening the hood and drivers door then turning your key to the accessory position. You will hear the throttle body whir and click. It may take up to two minutes. Afterward, the car will relearn your habit of driving and adjust accordingly.

Won't start, engine wont rev above 2000rpm


Have the alternator tested. You are providing a low charge to the battery when you jump it and when taking it above 2K RPM requires more amperage resulting in the engine dying and the rough idle
