I have a 1987 Bronco w/the 351w HO. I purchased it from the government with 29k original miles on it. When I first went to get it, the beast wouldn't start, replaced the computer and got her going(mouse chewed the wire). I'm thinking it sat for a while. Tires were all weather checked and had to bleed the brakes good to get them working. After getting her running she shifted real hard, I was assuming the vacuum module on the transmission. Drove it back and she still shifted hard. After replacing that I drove it a couple times and seems okay. But the truck also seemed to shift decent when warm, vehicle seems to drive fine at high speed. Idles extremely bad, you need to keep one foot on the brake and one on the gas with the thing in neutral at every stop, didn't run so poorly at low idle originally. Plugs, plug wires, distributor and cap/rotor look extremely new. I've done some online searches and seem to get a different vacuum diagram every time I look.. Just bought the Haynes manual and cant put my hands on it at the moment. Anyway would like to keep what hair I have remaining so would appreciate some thoughts on what might iron this out. I don't want to do the carb unless it's the last resort as I figure on pulling the engine in the spring and giving it a whole new set-up, just want it to run decent for me this winter. I'm thinking I should mention this thing came equipped with cruise control which isn't functioning, and yes so far it seems like every issue aside from the computer has been vacuum related.
