Loss of power 96 2.3 5 speed RWD
My 1996 ranger xlt 2.3 5 speed (8 plugs) has extreme power issues. She lacks power when im leaving a complete stop like a great hesitation to gain speed. Can almost hear like different levels of her gaining speed and through every shift (vroom vroom vroooom). the engine revs more than pulls. When I floor off the line, the pull she gives is nothing and the acceleration is slogish. to me the acceleration is slow which I don't think is right. shes a light truck and a 5 speed so the acceleration should be decent. atleast to pull away from cars. This is greatest when the temp outside is about 75 F and above. She drives much better when its below 75 F. So I have no idea what could be the problem.
OH WAIT! the accelereation and hesitation and loss of power is much much grater when the A/C is on sometimes it feels like its misfiring.
Things done to it, is a tune up (plugs, wires, air filter, oil change)
Changed both O2 sensors. Still gives o2 sensor code (bank 1 sensor 1)
sometimes Coil A pops up on the CEL and an evap code pops up everytime along with the O2 sensor 1
ANY IDEAS OF WHAT IS UP. PLEASE LET ME KNOW!
