Question about Nissan Cars & Trucks
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.

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

check transmission fluid.change fuel filter and air filter.try changing up on where you buy gas .because bad gas causes problems.

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.
