new here. got a problem looking help.
just purchased a 1998 ford ranger 3.0l just passed inspection theres 139119 miles. my check engine just came on had it checked out and it came up as cyl 6 misfire. changed plugs and wires its not that. the coil pack is fine. so i think its a bad injector but the plugs wet and the piston is wet. so i also thought it was a lifter/valve collasped. need help please wanna fix this before it gets worse thanks.
