2001 Nissan Pathfinder suddenly starts bucking around 2400 rpm

My 2001 Nissan Pathfinder suddenly started hesitating around 2400 rpm (when about to upshift). Also idle rpms swing from 500-900 instead of steady at 800. The car bucks hard at any speed when trying to accelerate moderately and speed decreases.. Ive had my engine light mostly on for two years, ive been chasing down that problem. Its a leaky air type emission code. When I erase the emission code it stays out for 75-100 miles. Ive got 6 ignition coils installed 4 years ago and I just now replaced the fuel filter. I'd appreciate any help.

SOURCE: 95 maxima rough idle

The injector could definitely trigger a misfire code, but you also mentioned that you had a mass airflow sensor code , that code code be responsible for te sluggish moment of the vehicle and rpm going up and down. However if you have a misfire onCyl#6 and the coil and the plug is good the ONLY other thing to cause a mis-fire would be the injector. To check the injector get a NOID light, you can get one at almost any auto-parts place. To use unplug injector plug from the bad injector and connect it to NOID light the light should have a steady PULSE/ligt flickering. If light flickers fine then injector is bad and will need to be replaced. If light doesn't flicker or flickers intermittently then you may have a bad wiring to that injector. Check if wiring is good, then you may have a bad cam sensor or sensor gear. Good Luck and contact if you need more help. Thanks for using FIX YA

SOURCE: Engine misfire on 2003 FordTaurus

I have a 2001 Taurus with a misfire in #2, I've already replaced all the plugs, wires, and the coil. I did a professional fuel injector cleaning at a well-reputable shop, I then had that same shop spend a day and a half to diagnose it, and it turns out that it is a sticking valve in that cylinder causing the misfire, have them test the compression off and running to see if that's the issue.

I have a 96 nissan maxima. It idles at about 1300 in park and 900 in drive. A friend suggested changing the spark plugs. Does this sound like a solution?


No spark plugs only produce spark to ignite the fuel mixture and do not control idle speed. Run fault codes to determine if there is a sensor fault as it should be idling around 900 rpm at idle and stay close to 900 in drive as the ECM will adjust the idle rpm to compensate for the extra load. Nissan maxima use special plugs that do not need changing

Pathfinder "cuts out" at 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.

I've had this issue and had the engine codes checked. It was a coil wire in one of the cylinders (nissan has ignition coils instead of the old plug wires) and this will fix the misfire if in fact that is what it is. To tell if you are misfiring, does the car idle smoothly? Does it misfire and kind of shake while driving where only pushing the gas peddel takes the problem away? Does the car feel like it may stall? Have it checked as if you don't and it continues it could burn out the catalytic converters and those are expensive on the nissan as there are multiples.

Can you not get any RPM out of it above idle, or does it rev to a certain point (say, 2400 RPM) and then refuse to go higher? If it's the latter, where the revs stop at a certain low point, check the mass airflow sensor out - on my 300ZX, a bad mass airflow sensor triggered the computer to limit RPM to 2400 to keep from damaging anything in the engine.
