Question about 1987 Ford Ranger
There are several causes why vehicle will start, but not run or idle.
1 Vacuum hose leak, or simply fallen off. That one is good for idle dropping off to zero.
The Fix? Locate the Hose and re-install, or replace. If the hose if loose, cut the old end off so that there is fresh rubber at the connection. If it is rotted, just replace.
2. Need new spark plugs and wires, perhaps a distributor cap and rotor. You did ths. Good for you.
3 Weak Coil, though this is not common.
4 Ignition timing
5 Air filter badly clogged
6 Clogged fuel filter, replace
7 A piece of Italian Salami lodged in the wrong part of the engine.
Remove, but don't eat.
Have a Happy New Year !
