i just found out yesterday that my engines been pinging or detonating .it gets thins strange sort of pinging rattling kind of sound when i rev it over 4500rpm.i always thought it was the cat convertor crapped itself.its only done this with the ported head we fitted. it might explain why i lost power after putting it on.
it dosen't do it all the time it must be the fuel i'm putting in or something.i had it tuned to run on 98 octane last time it was tuned.so maybe one of the servos i'm going to is selling crap fuel. do think it maybe just a crap tune? |
