HI,
If you still need help, you need to check the rpms at idle in gear. It should be at least 600rpms. If dropping below that, this will cause low enough oil pressure to turn the oil pressure warning light to come on. If the case, then the TP sensor, IAC valve and throttle body need to be checked for proper operation. Many times a good throttle body cleaning will resolve this.
If idle is going up and down, then check for vacuum or intake leaks.
