Check your crank and cam position sensors.
If both sensors are good (I doubt it) then maybe your timing chain.
Thank you how can you tell if there ok
You will need to have a meter hooked up under the dash (there's a plug in) and read the code or the meter display. A couple of different parts stores loan tools so you'll have to ask for it. Call don't just show up as they may be on loan already.
Also, when you get the code, Google your vehicle and ask what the code means. Good luck.
