Check engine light & stabilitrak

[Escalade1979]

Was heading out this am and at the same time check engine and stabilatrak light came on and truck started running rough. Sounded like it was stuck in v4...and shook here and there...

 

Any ideas?

Could be that a spark plug wire fouled or lost a connection. This seems to be some peoples issue in the past.

There is issues with coils and spark plug connections on this engine.

Just literally had this issue last week. Was a fouled/bad spark plug. After getting it replaced, I've put 150 miles on the truck with no issues. Much better gas mileage too, to boot.

Same issue a while back, spark plug wire fell off the coil pack on the DS bank, 3rd cylinder back from front.
