Stalling

[1994xlt]

Hey all, my Ranger has the 4.0 engine it is a 1994 it is stalling out when at or under a quarter tank of gas when slowing down to a stop sign or light any ideas?

No reply’s?

That's a weird one.
Leak in the pickup tube in the tank maybe? When you brake, the fuel shifts just enough to start starving the engine?

But it’s only when I’m slowing down and under a quarter tank and it only happens some times not every time it makes NO sense

First repair that T/B vacuum tube leak on your canister, then see how it runs.

Fixed it, truck runs the same but I guess ford put it there for a reason

You have three simultaneously threads about the same problem. I recommend scraping 2 of the threads and focus on just one of them. The stalling issue is the problem that I would persecute first; it will no dought resolve the fuel economy question and has already resolved the vacuum leak ..)

1) Your engine is stalling when you let off the throttle
2) you had at least 1 significant vacuum leak (you say that it is corrected, GOOD JOB!!)
3) it is suffering from low fuel economy.

I have no dought that these 3 conditions are related. As I suggested in the "mileage" thread, 1st determine which OHV 4.0l you have

It has the oHV 4.0 that came with it in 1994

That is not what I suggested you determine. I refered to whether it is the Federal (MFI-MAF/EDIS) or California Emissions version (SFI-MAF/EDIS) because that will determine which fuel economy figures to set as the models base.

Federal emissions
