It does have a MAP sensor on the ECU? Could you be boosting to high for the MAP sensor to "sense" it, and it will cause issues? I know here, for the G40's, they change it for a upgraded sensor, but have no idea which. Just a thought, not that I know anything about these cars...
i always fin d a gallon of petrol and a match soon solves the problem i reckon its time to do a step by step test on all the electrical items under the bonnet
Bump! Well after around 4 years! this problem is still there... Im now running a red top chip (Cheers Steve) and injectors, albeit for 300cc injectors instead of the 350cc injectors that im running. It hasn't changed the chracteristics of the problem at all... Ive rechecked the ignition timing, and its absolutely bang on 6deg btdc. Is it worth trying to go for 8deg? and see if it revs more responsively/stops the popping? Pics for views,just like on vortex...never understood it meself Neil.
no harm in trying the timing at say 4 degs and 8 deg....although id be suprised if thats the prob have you double checked it with a another timing light
Its a new timing light...well it was when the problem appeared Since used to time friends cars up etc and all is fine. Ive tried running it with the knock sensor unplugged, but the problem is the same Neil.
