Hi.
i have a 2005 ra rodeo 4jh1tc with vp44 pump.
I have recently fitted a diesel power chip and it has caused a slight knock or detonation issue.
when i give the engine a quick hard rev it does a single knock when revs are coming down, i dont know too much but it seems to be a detonating type knock.
My injectors are new, it did it with old ones too.
It doesn't do it without the chip as far as i can see, but im wondering if added pressure or stress from chip is making an existing issue more pronounced.
i can take chip off although i do like the power.
anyone have anything similar?
thanks
joel
