Hi all, I have a 2002 4 cyl ext. cab manual frontier. It started idling a little rough about 3 weeks ago. Eventually it started stalling at red lights , and also missing under load all without a SES light.
I searched through multiple threads to try and find a solution. So I changed the plugs, dist. cap and rotor, fuel filter, cleaned MAF all to no avail. Finally the truck threw a code and went into failsafe mode while driving. The code was P0103. So I Brought the truck to a dealer and was diagnosed as a bad MAF so I ordered a new one and swapped it out myself as well. It now shudders and idles erratically between 250 and 700 RPMs. SES light is now off but still runs horribly. Thanks for any suggestions! This is driving me nuts!
