ok its actually in my ranger but i seem to have the ranger station stumped...
so heres the skinny ive had this ranger for about a year. got it cheap cause it didnt run, no biggie all it needed was a fuel pump, did that, cleaned out the tank, new filter, FPR etc. okay so fuel delivery shouldnt be a problem. but id say 90% of the time it just has no power, like its pulling a trailer, or plowing through deep water, it takes off fine, but then hits a "wall" and you can feel it pulling back. no matter how hard or lightly i hit the pedal it just bogs. then at about 2000-2500 rpms (and sometimes its hard to tell because my tach also only works 50% of the time) its like a switch is flipped and the truck pulls just fine, seriously the change in power is that sudden and dramatic. So after pulling off a stop light and finally chugging up to speed with a line of cars behind me, i leave it in gear (5-speed manual) i blip the key off and on and at the next light its fine, power all the way through. I dont know where to even start testing... timing marks seem to line up for the cam, FPR holds vacuum, MAP seems to be working (runs worse with the vacuum disconected), vacuum is fairly steady bounces between 15-18 inches. I'm lead to belive it could be the ignition module (especially with the tach problem). I'm really leaning towards electrical because of the fact it can "reset" it by blipping the key. the check engine light comes on after about 10 miles IF the 10 mile mark is city driving, i can hit the highway forever without the CEL coming on but in the city it comes on, then after enough hwy driving it will go off. it will also go off when i bip the key... im lost REALLY lost and the afformentioned line of cars is getting old.. please please help me before i go crazy ... anything, any ideas no matter how far out im willing to try TIA!!!
