Ok guys first off I have a 03 Ranger Edge 4.0L 4x4 5 speed 175,000 miles TODAY. Newish O2 senors, and newish fuel pump. Other then maintenace parts never any problems ever.

So here is what happened, drove out to deer hunt and all was well, but not on the way back. I cranked it up and it died, cranked up and died, then cranked it with about 1/4 throttle and it would stay on. Then I pull up to the end of the driveway and it dies, I cranked it up and pulled out on the road. It will stay running (rough and bucky) if I stay in the gas, but if I go full throttle it will die as well. Every time I get out of the gas to change gears or to slow down it dies. When in gear and moving everything would stay on but the engine would die. I made it home, running every stop sign there was and when I pull in at home, it would idle just barely enough to keep it on. Need some info and some ideas, Im at a loss here. There was no check engine light or and thing un normal as far as the gages go, and Im half way through a tank of gas so I dont think its bad gas.

What do you guys think??
Thanks Robby

 

My first thought would be fuel filter clogged from a load of bad gas. Also could be a plugged catalyst, but it would probably not happen all at once like you describe.

 

I will give the fuel filter a try and get some fuel additive incase its got any moisture in it.

If any one else has any ideas let me know, heading to the parts store first thing in the morning.

Clean the MAF sensor and check the air filter. You can the MAF sensor without removing it from the housing. The link is just for general info. Might also want to swing by Advance or Auto Zone to have the computer scanned for check engine light codes.

as suggested I would

-change the fuel filter

-clean the MAF

-also check for Penidng codes

-check airfilter and intake

-clean IACV and TB

-Fuel pressure?

 

New part of the puzzle, I went out this morning and it cranked up fine. Idled up to 1500 and then back down to normal??? Still heading to the store to get some parts and cleaner. That kinda stuff cant hurt to fix any ways.

So I ended up cleaning my MAF and IACV and throttle body. Then changed out the fuel filter. Seems to be running fine now, the only thing that really stood out as a issue was maybe the fuel filter.

I will see how it runs, thanks for the quick responses

I would finish the maintenance, ie, airfilter/intake, pcv valve, check vacuum hoses, clean out EGR, clean battery cables, etc.........I also would see if I could get a code reader and if it happens again try and catch a pending code........also if it happens where it will not start be prepared to determine if it is a spark, fuel issue or both

*also if you have not done the following I would consider doing them

-plugs and wires(motorcraft or autolite only)

-drain and fill tranny and transfer case

-flush the power steering system

-do at least a turkey baster method on the Brake system

 

I will pick at it here and there. Last year I did the fuel pump, water pump, alternator, thermostat housing and sensors, idler pulley, tensioner pulley, belt, radiator flush, plugs and wires (motorcraft), O2 senors.

Plans this fall were to flush the power steering, and drain and replace the tranny and transfer and give everything a once over while under there.

As far as codes go, it never threw a light. Will there be codes with no light???

Thanks again for the help guys

 

When I first read the title of this thread I thought. "Well, duh"
