Sounds like it jumped time. Have you checked the valvetrain timing for accuracy, and wear? Also, what size engine is it?

An 89 Cavalier 2.0 has no carb.Its TBI.Might look like a carb,but its injected.
I bet you have a module go to heck.Its under the coils on the back of the engine.Usually they go when you key off,and then try to key back on.POP!
Has your TV ever blown up while you were watching it? A light bulb? Nope....usually pops when you feed it power (turn it on).
