IGHT i have been dealing with these codes since thanksgiving last year i have intake spacers installed dunno if that will help and a vias blockoff plate.. the codes will come on sometimes then one day i turn the car on and they are not there... the other day i washed out my engine bay and when i was done switched my intake to short ram and the car started stalling a lil after starting it.. i went bak and tightend the coupling and it ran fine... i was driving to tahoe and while on my way the car just had no acceleration.and sputterd. i was wondering could it have been the altitude?? 5000 or so miles above sea level.. so i went bak and looked at the intake again tightend er thing down and started headed bak home... and the car drove fine.. the next day i got 6 codes..

so here are the codes from my ob2 code reader

knock sensor 1 circuit low bank 1 or 1 sensor (and one is pending)

manf control veh spd idle spd control auxilary inputs (and one is pending)
wat does it mean when it says pending

lean bank 1 and bank 2

the car runs fine--only thing is at start up it will drop rpms a lil like it wants to die but pick bak up and keep steady..

any info will help please thanks.. have a lil road trip to cali comming up and dont want any hickups

 

The idle problem is an easy fix. Clean your throttle body. http://forums.maxima.org/6791650-post43.html

When you washed the engine, did you start it immediately and let it run until the engine was completely dry? Part of the problem could be something electrical got wet.

If you have a vacuum leak related to the spacer install, if any gaskets tore or the sealant wasn't applied evenly, all the tightening in the world won't fix it. Definitely sounds like you have a lean condition though, at higher altitudes, air is less dense which would aggravate a lean condition.

 

naw i did not turn it on right away like i usaully do.. wat could of gotten wet that would make this happen.. as for cleaning the throttle body is there a certain procedure to doiin this.. and also im in a pretty high altitude now wouldnt it be acting up from jump when i first installed the spacers... ?>?as for the sealant being applied how should i go about doin it>? cause on the instructions it said dont over do it on the sealant...

 

i thought untuned headers can cause u to blow o2 faster than usual because of no precats

 

got in the car today and had to leave quik.. so i started driving b4 the engine was heated up all the way and the dam hesitation again.. wtf.. but once it warmed up the car ran fine

 

as far as the lean problem-- intake spacers maybe????

 

cleaned maf sensor and lean bank 2 is gone.i also reset the codes to see if they would come bak but im pretty sure they will.. any info anybody>????

 

Yes, that could be an issue if they or any gaskets aren't sealing properly.

 

is there a way i can leak text or sumtin?

 

Only way i could think of is if you somehow ran smoke into your intake manifold with a smoke machine maybe

 

??? LOL dunno bout all that sounds scary...lol

any other advice

 

cleaned the maf same codes came up.... any advice... b4 it would take time for the codes to come bak but now they are commin bak in 20 min to half hour or so...also now when i start the car in the morning the idledrops a lil then rises to bout 2k..... then levels out.. neva did this b4 untill i washed the motor recently... please any advise will help
