Try TPS. Throttle positioning Sensor. This sets base idle. (Unless this model is too old for that sensor)

Check fuse able link a fat wire running from positive side of battery to fuse block in the engine compartment.

Check your battery cables on the battery remove and clean replace and see if that works.

Throttle position sensor

Got to have proper grounds attached, or you may have ruined the unit.

Knowing how to work on braking systems? Education My guess --replace a failed rubber flex hose I don't know how much moisture & rust is in the system, so is the caliper seized also

Check for water in the tank and fuel lines and the filter.

Clean throttle body,change air filter & fuel filter,put some fuel cleaner first.

is this carburated or fuel inj , if carb , the choke is stayin open , shoud work automatically if efi

Common problem. T/S lever is part of the "multifunction switch" that controls hi/lo lamps. It can be replaced by removing the lower shroud (3 or 4 screws from the bottom up). SW1093 @ Auto Zone about $66.

Check all the connections to be sure the wires are in good condition. Check the battery terminals and make sure they are making good contact. Make sure none of the pins on the alternator are not bent and are lining up with the connectors. Be sure none of the wires are pulled out of the connectors. Use a Volt meter to check the voltage at the alternator and at the battery. It should be between 13.5 and 15 volts. Also check the grounds to the engine. I hope this help you locate the problem.

If you could post more Information about the vehicle it would help. Is it a 4 cylinder or V6, and have you change plug wires or done any other repairs. Unplug the mass air flow sensor at idle and if the engine quits then the problem is not with that sensor, it is else where. It could have a bad timing chain and jumped time or if the timing belt on a 4 cylinder is worn out it could also jump time and cause a lot of damage. I don't know what else to tell you. I hope this was helpful.

It seems I have more questions that need to be answered. Have you got any on board diagnostic codes. If not you need to hook up a code reader to see if it is storing any codes that will let you to the problem. Most generally the lose of power is related to the timing and is controlled by the O2 sensors. another this is the mass air flow sensor located on the air intake tube next to the air filter. I hope this has been of some help. Good Luck

Here is a good forum to find your answer. http://www.fordrangerforum.com/exterior-tech/88010-brake-line-hose-replacement-94-xlt-2-dr.html A few few things to remember: Purchase fresh new brake fluid and have a clean MityVac pump (both can be purchased through AutoZone, NAPA, Orielys, etc..) , plenty of clean rags, brake line clamps to stop the fluid from leaking when you initially pull the line off. Be prepared to bleed ALL the brakes after changing the lines. When bleeding the brakes (after replacing the old lines) work from the caliper that is the longest distance from the brake master cylinder first to the shortest distance line.

1. go to auto zone and have them scan for default code it's free

Probably partially clogged tube, or sludge build up in intake manifold. Must take apart and look in these areas. I assume this is a high mileage vehicle.

Same as all vehicle issues or problems Things wear & fail You know the system with the fault You should have checked for OBD Codes & Googled what they are-problems & solutions

Looks like you need to replace the coolant temperature sensor for the computer. This will make the engine run rich all the time. You can simply check it with a scan tool with live data capability. With the engine warm read the engine coolant temperature. My guess is it will read very cold even with the engine warm. If so replace it and the truck will be running like new

Ok, it sounds as though your fuel pressure regulator or injector lines or injectors are leaking. What engine is in the vehicle? Is the engine light flashing? Does it start hard and blow smoke on startup?
