I have a Calibra 16 v, eco-tec- 1995. I have recently changed the plugs, gaps are fine, leads are fine, and it has just had an MOT emission test which was perfect. Any idea's why it is pinking would be greatly recieved!
Also can the rear camber be adjusted?

Yes the calibra has a knock sensor but there is so much the ecu can do. I had pinking in my calibra too for a while. Was kind of puzzled as the engine light did not light up to indicate a damaged knock sensor. But after cleaning my injectors, no more pinking! The garage who cleanned my injectors told me that 2 of them were really clogged. That would explain the pinking - the injectors were not able to deliver enough fuel to the cylinders to stop the lean mixture.

pinking should not be confused with the resonance all 20XE make at around 2500-3000rpm. fair enough if its just started doing it, get the injectors ulttrasonically cleaned.
I know its an old one but would be useful to know about this :)

Mine has a 'pinking' sound when accelerating from low revs. Tends to do it more when the engines hot.

Where does the XE resonance come from?
