Next on my list of issues on the most unreliable Ford they produced is a stalling issue.

It will run just fine and randomly it cuts out. It will start again after about a minute or two. This happened once about 2 weeks ago and today it died 3 times.

I think I'm having sensor problems because when it stalls I definitely have fuel but the engine doesn't try to catch and there is no obvious signs of wear in the ignition system. Then after 4 or 5 tries at starting it, with horns blaring behind me, it will start with a quite loud backfire and it will idle smooth and run perfect until it happens again. 99% of the time it runs, starts, pulls great except when this happens.

I pulled a 327 and 172 code. Relevent? I know one is a o2 sensor but that shouldn't cut the engine.

It is a 1995 f150 4.9L manual with an aftermarket MSD 6A ignition system.

OT: I'm into this thing over $6000 including 3 transmissions and 3 transfer cases, last tranny and tc was due to improper installation by a shop i will never go to again, starter, radiator, water pump, battery cables... I still need shocks, steering box, and I'm still replacing the PO's ****ing wiring job which has caused many hours on the side of the road. Plus the vandalism which has cost me hundreds more.

I've had it for 8 months now and taken it off road 3 times following my buddy in his stock Bronco that has never let him down.

Just my luck? Anybody else just have that one lemon?

I need some encouragement that this might be reliable some day.

Sorry about the rant but I'm thinking about burying this one with a tractor next to my old bug which is literally pushing up daisys. lol
(side note, explosives are tempting too)

 

NOOOO dont do that if you want to get rid of it i will come haul it off for you I need another project dont let a ford go to waste at least give it to someone it definatly has A HECK OF ALOT of potential. The 172 is the o2 code the other is
327 Electronic pressure transducer (EPT)/differential pressure feedback exhaust (DPFE) sensor/electronic vacuum regulator (EVR)
so idk what that is for but i am thinking you have sensor issues along with the po fubar wiring

 

I'm assuming it's the factory 4.9 right? I mean it's fuel injected, not carbureted, correct?

 

correct......

 

The 172 code sounds like you have a bad fuel pump or the fuel filter needs changing.
It is saying the the engine is running lean.

Continuous Memory DTC 327 indicates the EGR valve was closed further than normal or EVP sensor or circuit has failed with an intermittent low voltage sometime during vehicle operation.
Possible causes:

Poor continuity in EVP harness or connectors.
Intermittent open or short in EVP sensor or harness.
Damaged EVP sensor.

 

When it suddenly dies, can you hear the fuel pump running when you turn the key on? I know it's hard to hear over the horns blaring behind you.

If the PO did a hackjob on the wiring then I'm sure that's related to the sudden cutting out. You probably have a loose wire somewhere in the fuel pump circuit. I suppose it could be ignition related too, especially if the PO put an aftermarket ignition on it.

If it were mine, I would pull the aftermarket ignition and pull the necessary parts from a pick-n-pull yard to get back to stock.

Then I would go through all the wiring that the PO touched and make sure there are no loose connections or corrosion. I would bet that most of your issues relate to wiring.

These truck are very reliable when they haven't been mucked with and when they're properly maintained. I have put 10's of thousands of miles on F-series and Broncos and I have had very few problems.

 

I can hear the pump cycle and it sounds fine, no excessive noise, and the truck is actually running really rich. That is why I got concerned and pulled the codes.

Well at least while I am driving now wires have stopped falling out of the dash and arcing on my pedels. lol.

 

Now I can't get it to stall. And it's still burning rich. I think those are old codes since my check engine light has never came on.

 

Pull the vacuum hose off the Fuel Pressure Regulator (FPR) and see if fuel comes out of the nipple while the cold engine is idling, if it does the FPR is bad.

 

Where's that.
