Sounds like the catalytic converter or muffler maybe getting plugged up and the computer is putting the truck in limp home mode. Did you put a scanner on the truck. You might try to remove the 02 sensor ahead of the cat and see if it runs a little better it will not be perfect but should stay running if so do an exhaust check. When the cat or muffler gets plugged it puts back pressure on the engine and won't allow the fuel to be pulled into the engine properly.

I have a 1992 F150 4.9L. couple weeks ago it stalled out and wouldnt start, changed the coil it started right up and abot four more times that day then nothin. I have a new coil, new ecc, new cap,rotor,...


1) Have a look at the starter relay. Pull it out and ease the cover off and then check out the state of the solder joints. If any are dry and or there are signs of annular cracking around any of the power pins simply reheat with soldering iron to make good. 2) Check out your idle air control valve. Clean the throttle body interior and passageways to and from the IAC. Check that the valve is free to open and that it opens when at idle. 3) Check out your fuel pressure regulator (FPR). It sits on the end of your fuel rail. When the car is idling pull the vacuum line from it. The engine revs should pick up for a few seconds before running roughly. If you do not get this response apply vacuum to the FPR and this should cause the engine revs to drop. If by applying suction you pull fuel throught he vacuum port then the FPR needs changing 4) Lastly check all vacuum lines. Spray suspect areas with WD40 and if there is a leak there the engine will jump slightly in revs.

2005 f150 was running just fine and then all of sudden lost power and then shut off. Tried to restart and it started for second then shut off again.


Need more info., but same thing happened to me on my 01 f150, found out the spare key that I was using at the time, had a programmable chip that was going bad. Had new key programmed and solved problem. Hope that helps.

The car cranks fine (good battery) but will not


Hey all. I've had my 2003 in twice for the Crankshaft position sensor. In Feb 08 it fixed everything. My car wouldn't start when it had been running for a while. I'd pull into a gas station, then go to start it again and it would just turn over. Same thing just happened in July 2010. They replaced the crankshaft position sensor again, but now it's still doing the same thing. If I let the car sit for 20-25 minutes, it will start and run just fine. However, this time around the check engine light is on and it has never come on. I'm open to any suggestions as to what to try next. What is the PCM exactly?

Rough idling and poor fuel economy on 92ford f-150


This whole problem is most likey due to a sludged up intake and idle speed control valve, do the following procedure and it should take care of the problems, also run a couple of cans of LUCUS brand fuel injector cleaner through, I know u will see it is more expensive than other brands, but the thing is it works!
Here is the most common cause of surges and stalls at stops and low erratic idle speed and rough idle, it is the idle speed control air-bypass valve and throttle valve (IAC for short), they get full of gunk over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake

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.
