detonation last night!!??
so last night long story short i was gonna give bro a ride from his friends house...so i'm turning out from my neighborhood and caught the light, i barely did iand wen i take that sharp turn i usually jst slide the tail a little bit jst to have fun and feel it. well it had no traction threw 1st gear so i shifted into second, 'boosting like 8' and wen it gripped into second, the car suddenly shuts off OUT OF THE BLUE!! its never happened before so i was confused and i know my car verry well..looked under the hood and apparently the AFM plug came off the AFM while i was boosting...it happened last night and i was thinking that while in boost and the AFM comes unplugged it would LEAN the HELL outa my car cause detonation.. huh? after that it ran like the whole engine was unbalanced and no power wut so ever..i'm more then sure the motor blew but my question is...was the cause-'the AFM unplugging while in boost'? cause that sounds reasonable..thanks guys.

front rotor is blown guys..have no idea why..the only thing i noticed was wen i boosted and got out the car on the side of the rode, i saw the AFM plug un-hooked..idk if that has anything to do with it blowing but thats why it wasnt staying on..wen i plugged it in, it barely ran and idled..but as i said, as if i had no counter weight on the dam engine..
'unbalanced' shaky as ****. :/ thanks guys for the feedback though.

The stock fuel cut setup completely switches the rear injectors off under boost, but it shouldn't lead to blown engines.
Next time... install the plug retaining clip.

ahh but an unplugged AFM is not the same as overboost fuel cut. It will disengage the circuit opening relay, resulting in a disengaged fuel pump and a loss of fuel pressure. That will lead to a lean condition while the engine is still running. It's not a sudden and hard cut. And who knows what happened to the ignition timing when that plug came off.
