check engine light blinking, losing power, help needed!!
01' ranger. 3.0. Check engine light stays on, will start blinking when trying to go up a hill or accelerate. Have already changed plugs, wires and replaced coil pack not to long ago. Codes showed system to lean, changes O2 sensors and fixed that problem. Still having alot of trouble while driving. Could it be the coil pack again? Any advise is helpful.
