FUEL LINE IS PLUGGED UP AND NEEDS TO BE REPLACED. bE SAFE!!
If the check engine light is on have the vehicle scanned for any trouble codes. Write down the codes.
I suspect bad coil(s). Have the trouble codes read to know what is going on.

Check those two tiny vacuum fittings under upper intake (under front center & rear passenger side). They split/crack, The dealership service parts counter now has the updated new ones. The old oem style do not last long.
