well first off i wasn't doing anything stupid....ok here we go i was at the store i come out and start my car everything is fine i drive through the parking lot and stop at a stop sign again everything is fine i wasn't even going over 15 mph. i drive to the intersection and stop again and for the first 15 seconds idle is normal then suddenly my car starts shking and sounds like crap so i limp it home i was about 5 min away and it was freezing ***** out.

when i get home i pop the hood and i notice my airconditioning belt slipped off and my adjustments pulley is no longer there but how can this make my car sound like its blown i was able to drive it but it didn't have all the power there. it looks like the idler pulley bolt slipped back and somehow it hit my cas and threw it out?

just need some suggestions before i go fix it.

 

too new to know this off the top of my head but is that the same belt that goes to the alternator? If so it could have just been a voltage problem that will resolve itself when the alt is running again.

what is cas?

i got 14 volts running at idle i think its blown i started it up again and it sounds like a wrx i just can't believe it broke while idleing.

 

And all your spark plug wires are still on at both ends?

With a belt flying around and an idler pulley ejecting itself from the engine bay it is possible that something connected to the engine to make it run correctly has been disconnected.

 

Might as well compression check to confirm if its actually blown, then go from there...

 

did a compression test and the rear rotor is blown actually i think it's just chipped or maybe a stuck side seal...one face make like 20 psi the others are all good i might sell it i really don't have time to mess this anymore...

 

Oh man, I am so sorry to hear that.
