Engine Mechanical problem
1995 Nissan Maxima 6 cyl Automatic 146000 miles

1995 Nissan Maxima with very rough idol when stopped. Toke it to repair shop - they replaced #4 fuel injector, all spark plugs, and coil, and associated items. Worked OK after repair for about two weeks - not alot of driving (about 100 miles). Started doing the same thing. Took it back and they came back with P0170 and P0173. Repair shop says I need to now replace the #1 and #2 fuel injectors and all associated parts. I politely declined and drove away.

1) I can't find P0170 and P0173 on the list of codes for Maxima. The write up says Fuel Injector System Fault - Bank #1 and #2.
2) Doing a codes check myself on the check engine light I get 86 and 65 (misfire of #4).
3) Does a 95 have ODBII codes from 1) and can I get to them to verify? If so, do the codes from the check engine light link in anyway to the ODBII codes like listed in 1)?

Here are the defs I have for the code you posted.

P0170 Fuel Trim Malfunction (Bank 1)

P0173 Fuel Trim Malfunction (Bank 2)

Sounds more like it possibly a fuel pressure problem. Check your fuel pressure.

Also how did you go about getting the 2 digit codes you listed.

And go by your local Auto Zone and have them pull codes for you they will do it for free.

Post findings here in forum.
