my 95 bird 4.6 seems to have a mind of its own
Hey yall, new to forum and am enjoying every bit. Anyways picked up a 95 bird 4.6 and was throwing codes. Put on reader and came up with o2 sensors and maf. So replaced maf and jacked up car to find that o2 sensor was unplugged. Plugged back in and no more codes thrown. Now for the mind of its own part; cold or hot my bird will shoot the rpms up to 1500 to 2000 then drop to 400 or so and then back up again. And sometimes will stall. Now if Im at a red light and then it starts acting up I almost rear ended the guy in front of me. Yeah pretty scary. Any help would be greatly appreciated.
