Nissan Repair Questions? Ask a Mechanic for Answers ASAP
do you have a scanner to view your fuel trims?
I thinking mass airflow sensor issue.
I dont know how its running? but you can unplug to maf sensor and it should still run better if the maf is faulty
unfortunatly no, not acuratley anyways. if there is a valve on the fuel rail you can press it to see if there is fuel there.
kind of a last resort too, you can give the fuel tank a smack with your fist. IF the fuel pump was stuck, this can get it working again, but it will do it again if the pump is weak.
THe biggest info you will need is does it have 1.spark 2.fuel 3. injector pulse
can you explain exactly what its doing for me ?
they put 4 cats on it for emission regulations. it was probably failing standards, so they just add more.
as for the cats doing it all of a sudden, it shouldnt.... thats the funny part. cats plug over time or at least in a couple weeks witha bad running engine.
did you unplug the mass airflow sensor? sand see if tehre was a change?

New tech here.
Lets not over complicate this issue.
If you started having a misfire after your last fill up, then you almost certainly got bad gas.
The easy way to check this is too open the fuel feed line and crank the engine and pump fuel into like a large clear mason jar. If you let it sit and the fuel stays a perfect consistant yellow than it's likely normal, but in your case you will probably notice sediment or seperation from the water and fuel.
