SOURCE: fuel air mixture too rich on a 98 nissan pathfinder

My guess would be a fuel injector or fuel pressure regulator problem, or a Mass air flow sensor.
The O2 sensor does not come into play until the engine has run for a couple of minutes.
Is the check engine light on ?

Hi,

Thanks for using FixYa.

The answer is... Yes you can... All it requires is patience and skills. You'd need to squeeze the engine in your car. This might require you to cut some chassis parts in your engine bay just to accommodate such big and powerful engine. Best wishes with the engine swap buddy.

Thanks. Have a good one.

SOURCE: Nissan Skyline Engine Production Date--

RB20-763643A production date will be between 1989 to 1993.--------- ----- This is what Nissan service details says for reference :----
Nissan RB engine is a 2.0-3.0 L straight-6 four-stroke petrol/gasoline engine from Nissan produced from 1980-2004. -------- The first RB20E/ET/DE/DET engines were fitted to the HR31 Skyline. The early twin cam engines are generally referred to as 'Red Top' engines because they have red cam covers. The early twin cam engines featured the NICS (Nissan Induction Control System) injection system, while the later twin cam engines used ECCS (Electronically Concentrated Control System). Later versions which used ECCS engine management, discarded the twelve tiny runners for six much larger ones (though they retained twelve ports on the head, so there was a splitter plate). The RB20E was also fitted to some Holden Commodores (the VL Commodore) sold in New Zealand and Australia, and also to the A31 Cefiro and C33 Laurel. ----- Laurels, Skyline and Cefiros used the second (1989-1993) series RB20E/DE/DET. -------- This will help.Thanks.Helpmech.
