I have replaced everything on this thing from fuel filter to air filter, mass air flow sensor, coil pack, wires and plugs, cam position sensor. I am baffled and dont know where to look for the problem now. I have had the fuel pump out to replace it too bu when I went to put the new one in it was the wrong one. they sold me one that wasnt for flex fuel. Parts are hard to come by for this thing where i live. The truck runs great except for when you accelerate hard taking off or passing someone. Then it cuts out, rpms drop and it comes back over and over until you let off. It doesnt do it all of the time. It can do it really bad one day and not at all the next. I drove it about 140 miles yesterday with no problems. Go again today and it does it terrible. Any help with this would be greatly appreciated....

Re: ranger 2003 ranger 3.0 stalls when accelerating
I guess I have to ask is the CHECK ENGINE LIGHT ON? I have seen a crack in the air intake hose that only opens up on hard acceleration because of the engine torque Im sure you looked at that, just mentioning it.
Has a TPS been check don't just replace parts test then replace sure its slower but sure is less expensive and you learn something too.
If the engine light is on, get the code then contaact me and Ill tell you how to TROUBLESHOOT AND DIAGNOSE NOT JSUT CHANGE PARTS

ok lets start with the codes they say your getting. P??? which 1's and how many. there are few o2 sensors, are they next to the Exhaust next to the converter? MASS AIR FLOW -MAF use this, for now i am guessing, until i see the correct codes your are getting. this could be the 1 you may have below, please read it........
Faulty mass air flow sensor
- Intake air leaks
- Dirty mass air flow sensor
- Dirty mass air filter
- Mass air flow sensor harness is open or shorted
- Mass air flow sensor circuit poor electrical connection
Before replacing the mass air flow sensor, try replacing the air filter and cleaning the air flow sensor with low compress air or mass air flow sensor cleaner. Reset code and drive vehicle. If the code comes back, it may be necessary to replaced the mass air flow sensor.
possible symptoms Engine Light ON (or Service Engine Soon Warning Light)
- Engine stall
- Engine running rough
- Excessive fuel consumption
- Excessive smoke
the code is generated when An excessively high voltage from the sensor is sent to Engine Control Module (ECM).
going to ask a scary question, no insult intended. have you checked the OIL when was it last changed. Air filter fuel injected system uses air filter was it changed last... fuel filter, not sure how many it has, may want to have that checked. spark plugs have them checked look at them, they maybe fowled. so here is a link that address the issue.....
ok so much done owell next is the mass air flow to be checked then the fuel regulator to check pressure and the fuel pump for pressure and then check the cat,s for back pressure wood be my next thing and Last is the how many Km,s does it Have ?sounds like filter needs lookin at in the tranny if she,s got High Km,s if not then check the intake for leaks it,s Plastic so don,t hurt gone this far Let me Know What Happens,s Thank,s
many thing cause engine stall out while driving faulty mass air flow sensor. stopped up fuel filter,faulty fuel pump check fuel pump fuse and relay.faulty alternator look for lose wires on alternator or ignition coils to module.faulty PCM. best code scan vechicle first before buy new parts but first thing to do replace fuel filter see if problem still occurs.
SOUND LIKE THE IDLE AIR CONTROL OR MASS AIR FLOW SENSOR WILL CAUSE VECHICLE TO STALL OUT.ALSO BAD GASOLINE. BAD COILS OR BAD FUEL INJECTOR.STOPPED UP FUEL FILTER.AND A INTAKE LEAK.MANY THINGS CAN CAUSE VECHICLE TO STALL.
Start with smaller problems and check the fuel pressure regulator, the mass air flow sensor for these vehicles is pretty pricy. Is the check engine light on? If so, head to your nearest auto zone and have them check for trouble codes. If the check engine light isn't on, its not likely your mass air flow sensor
