Car Information:
Nissan Sentra
Year: 2001
Engine Size: 1.8L
Trans: Manual

Issue / Question:
Code p1130, low power low rpms, runs better at higher rpms, runs better on dry days, probably MAF sensor needs changed. If I remove IM and clean and change O-rings, clean tubes, will this help?
Also a squeak from under the valve cover, I resealed the VC gasket, should have changed the pcv.
I have replaced the upstream O2 sensors and cat conv and ignition coils& 2 belts, power steering pump & alternator.

Answer:
I don’t have a listing for a P 1130 code, Have a 1126 and a 1132
but nothing in between. I would need to scan the system and see what you have going on.
