okay so here is how it happen. When removing the #4 plug to change my 96's plugs it was drenched in oil. with a flashlight and closer look i noticed the rubber grommet/gasket between the intake mani and the head wasnt there, letting oil flow down into the resevoir. So a trip to nissan and 2 hours later i took the intake mani off and replaced the three rear grommets/gaskets and thought i was done. Here comes the check engine light great. and then i checked the codes here is what i got.
03/04 Knock Sensor
02/10 Fuel INJ sys left bank:lean
01/15 Fuel INJ Sys Right bank:lean
13/02 MAP/BARO SW Solenoid/Valve

After reading more on this site i learn that the lean fuel codes is related to possbile intake leak.. yup thats my guess.. given the thing just came off... and im also thinking the knock sensor is just a related code to this...tell me if im on que here.
but that last one i have no idea what the heck it is.. and when i tried to further investigate it on the site. i cant find anything that would allow me to view it... says i dont have permission.

Here is what im thinking of doing as solution.. help would be nice here since this is the first real wrench work ive done on the max (im integra owner sorry) i was thinking of getting a gasket kit given that i didnt replace any of the gaskets when removing the intake mani... didnt think it was a big deal and then putting it back on with fresh gaskets in hopes of elliminating any intake leakage..

is there any other advice or tips anybody can give me to help me through this process... ? thank you in advance.

 

This happened to me once too, actually to my friend who I let drive my car. I'm not exactly sure what it was but all I did was try to clear the codes and it went away. When he got the code the car run kind of like ***. Drove around cleared the codes and it ran fine. Another thing, the bolts may be on too loose, not to spec. Also another time I got a running lean problem the o2 sensor was messed up...

 

ill try resetting then... anybody else?
