Hello. Most of the time this is caused by an issue with the variable valve timing. Since you do not know the history of the engine it may have some sludge built up inside which is going to affect the variable valve timing. I would flush the engine oil and then run some seafoam through the intake to see if it clears up. If the problem persists then it may need a fuel injection cleaning. If you want to have this issue thoroughly diagnosed and repaired, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose this.
