Hi all hopefully someone may be able to help...I have recently been trying to bring my 325i back to life after nearly 10 years in storage. The car was running fine until I changed the coolant and thermostat now it is hesitating/misfiring and generally running rough....so far I have changed oil/filter/spark plugs and it was running perfectly until one of the coolant hoses split , the eng temp nearly went into the red but I switched it off asap.....
So really my question is why would the car run bad after a coolant and thermostat change when before it was running perfectly?
Any ideas would be appreciated......
