Car jerking and smell of gas
My evo 8 has been jerking at 150kph, once in a while sputters even at low speed WOT..
So i replaced plugs, coil packs and cables but still this problem has not yet been solved,
the car smells gas on the engine bay after a bit of spirited driving, where do i check next?
could the gas smell be related to the jerking problem?

Un educated guess but it could be a boost leak from a connection point between intercooler pipes. Follow the fuel feed and return line inspect for cracks/leaks.

Okay my wideband says the car is running rich, at wide open throttle it goes upto 10.0afr which is the richest the gauge can read, pretty sure it hits the 9s,
its more like a hesitation feel,

did a boost leak test, found a massive hole in the intercooler, got it welded properly,
apparently the jerking is still there.
