Has anyone come across this?

I have a power FC , and when the car is warm the idle timing jumps around from between 6-20 degrees..it does it intermittently ...sometimes when i switch the heaters off it triggers the timing bouncing around, only does this on idle...not when throttling

Ive swapped out the CAS but it doesn't seem to be that

Any ideas, apart from this the car drives brilliantly

It's quite common, that's why a lot of people run crank trigger kits now

Didnt realise that it was quite common....what i dont get is its jot doing it through the rev range only on idle and when warm

Did a sensor check and the 02 sensor voltages are wayyyyy off...one is at 1.23V other is 0V and keep fluctuating to nothing sensible. My thoughts were they shld both be around the same volts

Will change these and see how it goes

It only does it on idle and when car is properly warm i.e. a good thrashing

I read somewhere that the lambdas go into closed loop once warm?

Will see if it changes anything
