long story short, for the past year or so my 95 has ran like garbage. rough idle, loss of power, sad gas mileage, misfires galore, and a plethora of codes. my fixes have been a fuel filter, distributor cap and rotor button, plugs, wires, gas cap, egr cleaning with new mesh filter, and a can of sea foam just to name a few. all these things were helpful if only for a few miles, but in the end it all came down to two things. a new cam position sensor, and a slightly used spider injector along with the two fuel lines under the plenum that feed it. im pretty sure the bad sensor was to blame for at least a little bit of the roughness due to unrefined fuel delivery. but the spider was a wreck. three of the six cylinder lines were to a great degree melted and full of holes. i have no idea why. do you? also, one of the main feed lines had a 1/4 in. slit in it. now that ive got all that fixed, she runs great. smooth, plenty of power, 18 miles to the gallon around town, no misfires, and no codes! i cant tell you guys how much i appreciate your help, without this forum id be nowhere close to being fixed. i didnt post much, but i read a ton. special thanks to kyle, seems like every useful post i read you either wrote, or referred to. hopefully i can return the favor and pay it forward to some other poor tortured soul on here. youre all a great bunch of dudes, i mean, how could you own a blazer and not be?
