Hi, just wondering what is the best way to get rid of detonation. take out some timing? I havent adjusted the timing at all, still at stock but i was using 89 octane gas until recently when i went to 87. now i can hear pinging at low rpm. from 1k to about 3k, only in 1st and 2nd gear.

the motor is a stock d16y7 w/intake.

any suggestions?

thanks

no ideas?

 

How many miles ?

 

not sure in miles but 180k kilometers. im pretty sure i need to adjust my valve lash as well. just have to get around to doing it.

 

bump for this... i want to know too, i too always seem to start to get detonation in my cars even after i do regular services... what gives?

 

check the timing=good place to start

then what?

 

double check cam and ignition timing

 

just do that first then....... even though OP said timing was still at "stock" someone may have changed it before i would start there
