Question about 1992 Ford Ranger
The problem started out slow, gradual power loss, developing into rough running at speed, back fires and stalls, bucks and snorts, engine light comes on and loss of speed and power, if I kick it down it kicks in and seems to straighten out and the engine light goes out, also rough idle. This truck was run on E-85 for many years and it ran very well on it. Now am running regular gas. Replaced Oxegen sensers thinking that might be it. Seemed to help at first but when I took the truck out for the reset drive it felt like it was going to have to be left by the road side.
Check and see if the EGR valve is leaking, to check this spray water on it at idle, if the water steams off the valve is leaking and is the source of your problem, also are you sure you hooked the new DPFE sensor up right? re-check it..

SOURCE: truck runs rough
Sounds like one of your chambers isn't firing. Run your car for a few minutes, shut it off then pull your plugs one at a time and see if one of them is wet. Might just need a new plug.

its right behind the intake manifold. its a B*&^h to get off but you need a special tool you can get a most auto part stores. you have to make sure your #1 piston is TDC on your compression stroke. then drop in your sensor, align it to what your specs say

Generally the computer is reading a problem with the fuel pressure being to high or to low. The ICP is one problem it could be and you changed it. The other could be Fuel pressure regulator control solenoid or problems with the injector (s).
