Question about 2003 Nissan Pathfinder

1 Answer

Pathfinder "cuts out" at 2,300 rpm

Problem started suddenly. Cuts out, will not accelerate beyond 2,300 rpm (acts as though fuel line is cutting on/of, on/off, 10 times per second). I am convinced it is electronic..? Idles fine, accelerates perfectly until 2,300 rpm. Probably not fail safe mode as the car has same symptoms in idle. In park you can idle and accelerate like it did brand new, no hesitation, perfectly smooth and strong..UNTIL 2,300 rpm then cuts out, chugs, it doesn't stall it just won't accelerate beyond 2,300. On level ground or downhill you could run it 100 mph (as long as you don't rev beyond 2,300 rpm), uphill probably not since ultimately you would probably rev beyond 2,300. Code says replace MAF. Sure doesn't seem likely since it runs perfectly until the magic 2,300 rpm.

Replace your MAF, its a little pricey around $280.00 or so but this will clear the code but make sure you have the ECM reprogrammed to perform a "learning" sequence since sometimes the code will not clear even though the vehicle will run like new. This reprogramming will most likely have to be a dealer performed procedure.

    Rplace your MAF, it's pricey at around $280 or more for a new one, but this will clear up the problem. Unfortunately this will not clear the code, this will have to be done most likely by a dealer who will have to put the ECM into "learning" mode for the new sensor. probably about another $60 to $100.00.

Honda accord making a whining sound and loss of power


Ok I need some clarification here. Is it surging/chugging when accelerating? Is it having shifting issues? All the time? Or do you mean it misfires/cuts out at high rpm? (I assume you know there's a rev-limiter that will cut cylinders to keep engine from over-revving). What rpm does it cut out? Is it happening intermittently, or constantly? Also, is the car modified/raced and what condition is the engine/powertrain? Do you have mostly stock Honda tune-up parts in it? Honda's don't perform to their potential with cheap aftermarket plugs/wires/ etc. installed. Start with the basics here. Check the ignition system, fuel system/pressure, etc. Could be bad fuel too. Did you fill up at a small rural no-name station recently? Good luck.

When accelerating fast the engine cuts out suddenly then returns to normal multiple times. If I try to accelerate at a lower pace then it works fine. It feels like an electronic problem


Engine ECU is provided with a high RPM ignition cut off. Perhaps that is what is confusing you. When you accelerate at a fast rate, probably you get higher RPM's and the ECU cuts the ignition to protect the engine from damage.

My car over rived wail driving n cut off same time any one know what is it?


If you experience a sudden failure in any drive line component the because you have you foot hard on the accelerator the loss of resistance on the crankshaft will allow the engine to rev up un controlled until an over rev sensor cuts of the electronics. Find the reason for the sudden rpm increase from fault codes and replace faulty items.

stalls are caused by over 50 reasons. guessing is impossible or very expensive.
enter: Diagnosis,
you take measurements, and find the failure path then work that path like bird dog.
2.5L 4cyl engine. I just sold min last week. with 5sp M/T
cuts out, does that mean the engine stalls?
we need to know what it really does.
1: stalls (engine rpm drops to 0 RPM)
2: engine rpm drops to 300rpm and shakes.
3: power loss from engine?
4: only stalls at stop signs...?
5: bogs all them time, same as #3
6: engine misfires (shake)
7: bogs only on throttle TIP-IN then recovers.
8: bogs only on hills.

i wait.
when dead, is spark lost?

Car stalls when stopped, cuts out when accelerating to HWY spds.


You could have a bad or intermittent fuel pump. Not a cheap thing to have.

An OBD 2 scanner can read fuel pressure on the drive to see if your fuel pressure drops off at odd times to confirm. It can also tell if there are transcient vacuum leaks at idle which the engines idle air control cant compensate for.

Do the plugs, wires and cap too.
