just spent 500 bones
A wierd and very loud rattleing noise was coming from the engine. During diagnosis my dad and i determined it only happened with the fan belt on. So i replaced the power steering pump, water pump, and idler pully, and tested the alt. All of them were working in good condition. There went alot of money. I jokingly asked my dad if he could turn the crank at the crank pully, he reached down and spun it, EUREKA broken harmonic balancer. That job we couldnt do ourselves, dealership did it for $320.
Heres whats bothering me, the car seems slower, less pickup, and the idle at 200 deg is ~1100rpm
should i wait for the comp to relearn or should i disconnect the batt cuz there might be a bad code in their. or am i looking at a bad IAC?
