The timing can't be off, it's either right or the whole system is malfunctioning. Unless you have done work to the cam or crank sensors, it cannot be off like a distributor.

Sounds like a plugged cat.

I can't remember which year you have, but many of them have 4000 rpm limiters when in park or neutral, so don't let that alarm you.
