I am an old school classic restoration guy for 45 years. Pretty good mechanic for older stuff. Not an idiot about new vehicles. Have scanner. Code shows low voltage to maff. Voltage is 0.2. At idle. Not increasing, when rpm raised as Im sure it should, I believe. This thing stumps me.I have a 94 Ranger, 4.0 5 speed. Will start and run. While driving it cuts off after 5 seconds, let off gas and it is running for 5 seconds again ( cuts off when accelerating. Only). Will cruise ok at speed, until you apply more gas. And it will cut power for 5 seconds, then every 5 seconds the same over and over. Heres the kicker. If you don't let off the accelerator. It wont resume running. Hold the pedal down an inch, or more and the truck doesn't resome running. Will slow to a stop unless I let off pedal then its running again I have replaced everything fuel related code reads low voltage to maff.(Cleaned it, then replaced with new maff (twice to be sure of new part being good)replaced throttle pos. Sensor. Fuel filter. And more. My question is, has anyone seen this weird problem before and if so whats the solution. Im at a loss. And stumped. Help L.B.
