i already have posted this on other forums and i cant figure anything out.
so one day cylinders 4 and 5 stopped firing randomly. i checked compression and its fine, pulled plenum and checked injectors and fuel rail, all fine. no spark when i ground a plug to the plenum though. i checked the ptu and cas, both fine. swapped around plugs and coil packs. miss stayed on the same cylinders. i threw codes and threw a code 34 (det sensor).. im assuming its unrelated (i have a slight tick from a loose bearing)... i cant figure out what the hell is wrong..
