I have an 86 ranger with an 88 computer, a 90 motor, and 700,000 miles thats driving me crazy . it will always start right up and runs ok sometimes but it seems slow. other times it will run rich start missing and chugging, the idle will roam around, and it will stall. if I am driving and it starts doing this I can get it to run ok again by flipping the key off and back to on while moving and it will pull itself back together for a few minutes.
I checked the codes it has had an o2 sensor code since i changed the computer also has a secondary fuel pump circuit failure code. i've replaced both the o2 sensor and its plug. and my pumps seem to be working just fine.
what I've replaced so far. when I got it the computer was still an 86 computer. I swapped it to an 88 computer ( no egr). it has a new tfi module, iac, new coil, plugs, wires, rotor, cap, both pumps, 2 new injectors, air charge temp sensor, tps, map, all vac hoses have been changed or deleted, o2 sensor and plug since the old one became one with the exhaust.
I'm running out of ideas of what could be causing this . anyone have any suggestions of what to try next.
