Aoa fellow pakwheelers,
I swapped m16a vvt engine in to my eminent.
I was facing knocking issue.
I scanned the car.
There weren't any codes.
I'm using m16a tcm and ecm
Pkdm version one.
It doesn't have vvt output.
So vvt is connected.
I changed the plugs to iridium that's rated on m16a vvt.
Coils are good.
Used hi octane.
On hi octane the knocking sound becomes less but still knocks till 3krpm and then on 3200 rpm or above knocking disappears.
Plugs are brown.
Changed the injectors too.
Coolant sensor is working properly too.
While car is neutral and even then if u throttle the knocking sound comes.
Car isn't missing at all.
What could be the issue?
To me it looks like it's running advanced below 3k that's why it's knocking that means vvt needs to be connected.
Please anyone else share some valuable suggestions that what could be the possible issue?
