I have a '99 Ranger 3.0 flex fuelthat runs fine cold...when it gets warm it starts missing on the right bank..Cyls 1, 2 & 3...I have replaced the plugs, coil pack, wires , checked compression. all cyls have 130-140psi..I have put a new O2 sensor in the right side, cleaned the mass air flow sensor and the cold air sensor in the intake tube...Can anyone help
