Ignition ping.
My Xantia 2.0/16v XU10J4 has a slight ignition timing ping in 5th up hills or hard acceleration in 3rd/4th/5th gears. It’s only slight but if it’s fixable I’d like to track it down.
Anyone know the most likely/common cause in 2.0/16v. Should I be thinking of throttle potientiometer and/or knock sensor? Or should my question be `how long is a piece of string!’
Cheers

it doesnt have a knock sensor but it does have a cam sensor which is about the same thing to check it, expose the connections "do not remove the multi plug" then using a volt/multimeter test terminals 2 and 3 voltage should read 4 volts fluctuating, if that's ok then try a better petrol station or use Optimax ( which I think is well over priced ) or use a fuel booster additive.

STP is the most used try some then go to the sensor, sensor is on the right hand side rear of the cylinder head.

Update:
I’ve noticed engine only seems to ping when engine is warm, 80/90oC or above. I’ve tried to re-create conditions with cold engine and so far… No ping.
Also stumped up the extra 3p a litre for a tank of 97ron. Initial test made no difference but I’ll see how things go after a week before trying octane fuel additive.
