Pinging

[dstylez]

My r33 started pinging badly when i started it this morning. I haven't driven it today, just in case. I'm wondering what could be the cause? I've always filled up the car with optimax or synergy 8000. Will a simple ECU reset solve this problem? Or do i have any other problems? The only engine modification i have is a panel filter, and a bleed valve (set to 7psi). Any thoughts/ideas would be appreciated.

Timing belt slipped a notch? Not sure if that would cause pinging or just break something, someone more knowledgeable might know.

Check that your CAS is secure...doesn't take much of a rotation to get it pinging.

also your fuel pump might ben one the way out get that checked cheers

the first thing i would be doing is check the timing , if u got stock ecu u have to do it with a timing light .

are you sure its pinging? if you just started it i cant imagne it to ping on idle. it could be a lifter noise or piston slap?

I've never heard of an engine pinging at idle. My timing belt was loose when it got here from j-land and that made a noise (cant remember what sort) at idle. Pinging doesnt normally happen till the cars on load, ie: 4000+rpm with 100% throttle. When the days were warm in Perth and I still had the stock i/c I could always hear some pinging around 4000rpm on hard acceleration when running 12psi on the ebc. If the cars fairly std I cant think why it would ping at all.

i never knew pinging occured at idle, its probably a lifter noise
