engine misfires on #2 & #5 cylinders randomly. Spark plugs, wires, coil pack, 2 injectors, camshaft & crank position sensors, & computer have been changed. A compression test has been performed & all cykinders are 125 psi or greater. Checked valve springs & pushrods on all cylinders. I have replaced the new parts as some might have been defective with no improvement in driveability. I have performed an engine diagnostics through OBD II port and it will show misfire on #2 or #5 every time. Has anyone ran into this problem???
