I have a 87Ford Ranger 4x4 auto 2.9 efi .When I start it no trouble then the idle drops and it almost dies it does this till the engine warms up.Can anyone point me in the right direction on this,also there is a green and red plastic hose that come from the fender the red one is broken where does it go to.I bought the truck from a classified ad and is my first ford ever,I"de like to see it running properly as it"s a nice truck.Any help on this would be greatly appreciated

With a littl more detail, I might be able to help you. For example, there are no vacuum lines going to "the fender." It might go to a component mounted to the fender (or the air filter housing or the firewall). Which fender? A while ago (so I can't remember colors) I replaced all that crappy, rotten plastic tubing with regular vacuum hose, but that means I can't determine where "the red one" went.
A lot of rough idle issues boil down to a dirty idle air control valve (IAC). Pull it off of the upper intake manifold and clean it real good.
And while you're leaning over the passenger side under the hood, find the EEC-IV self-test conncetor, jumper the appropriate pins with a paper clip, put an anolog voltmeter across the postive terminal of the battery and the "self-test output" pin (see www.dalidesign.com/hbook/eectest.html), and run the self-tests to see if the computer sees a fault.
