in one of my previouse threads it was reported that the probem was caused by either a feked up ecu or the crank sensor. Changed crank sensor got codes cleared p0607 Control Module Performance and p0325 Knock Sensor 1 Circuit Malfunction (Bank 1 or Single Sensor).
This lasted a week and now there back.
related problems - dimming of the headlights and lack of power when accelerating within 5 mins of starting then after 5 mins it goes back to normal.
had alternator and batt checked there all fine.
any info would be an advantage but alternatly how much can a replacment ecu cost or a 2nd hand one to be reprogramed?
