Mystery misfire on cyl 5
Hey so maybe one of u guys has any idea. I have a mystery cyl 5 misfire.car ran fine, parked it to replace my vtc oil seals. I replaced the vtc oil seal on bank 2.put everything back together started the car and suddenly have a really bad mis on cyl 5.so not even the same bank. I replaced the coil and plug, I swapped new coil and plug even with other cylinders, replaced coil connector, replaced valve cover gasket, replaced fuel injector, replaced cats with test pipes, compression test was fine, o2 sensors are fine, maf readings are fine and the fuel pressure is good. But I still get a misfire on cyl 5.idle is steady but car I'd shaking bad on idle.
