Question about 1997 Nissan.5 Altima
I have a 1997 Nissan Altima that has started having an irregular idle. It is almost like someone is hitting the gas and releasing and it jumps between 300-1000 rpms. it was throwing codes for the stupid knock sensor, multiple cylinder misfire and the O2 sensor. I changed the plugs and wires, fuel filter, air filter, front O2 sensor, both belts, distributor cap and rotor, spray cleaned the MAF and replaced a cracked manifold. I also ran a bottle of Gumout fuel injection cleaner through it. The idle has actually gotten a little worse after doing all of this. Next i'm going to check all vacuum lines. But i think it may be the dreaded MAF sensor. Any other suggestions?
The description sounds like a technical Service Bulletin Nissan came out with on your car. It fits your description to a "T".
However, the codes you are getting are not what the service bulletin reports. The code they say it sets is DTC 0400 which relates to an irregular EGR operation, causing a problem where it will not maintain an idle or Will idle roughly. There is not a recall campaign on this item.
As far as misfire problems: Nissan had a service bulletin out on problem ECM's which caused this problem. Check with your local dealer. This may possibly be covered under warranty.
The reference number is NTB97-026 The bulletin was issued March,12,1997 There was no recall on this item.
Good luck to both of you.
