I got my maxima in 08 here is what i have done so far

passenger side Wheel Hub
2 Oxygen Sensor
replaced radiator
replaced all motor mounts
replaced KYB GR-2 struts and new boots
replaced valve covers
switched to Akebono Street Performance Pads pads and Centric premium rotors
changed spark plugs
changed engine coils
and normal routine stuff oil,tires, etc

Current issues

• it is believed that the ecm is dying (symtoms when trying to accelerate sometimes it idles out and the abs light comes on)
• Small oil leak somewhere and engine is burning oil (it needs about 3 or 3 1/2 quarts of oil before a oil change on a 3,000 mile schedule)
• Pre-cat needs to be changed

i would like to keep it long term. Things i would like to do is

• upgrade the sound without a amp i like how new cars are they have good sound without a amp
• get all the interior clean ( i have the cloth type interior)
• Steering wheel repair its starting to fall apart slowly

I would like some suggestions on how to address the issues and long term items....

ummmm, none of that stuff is 'retrofitting'

i dont like the flashy stuff rims, dropping the car and all that. I like stock and reliability! I guess what i am looking for is suggestions on how to solve the current issues listed, ideas on the things i would like to do and how to keep it in better shape.....

Fix the major issues, that is a lot of oil usage. Maintenance. I wouldn't worry about whether you want flashy stuff or not when your car is falling apart.

How many miles on your car ?

Firstly, you should have posted that then, not 'retrofitting', it's misleading, the title of your thread should be a brief description of what you are posting/asking

Second, I've fixed your post and hopefully answered your questions with a little common sense and a small bit of knowledge from lurking on the .ORG:


Putting a stereo, cleaning up, etc, etc, are all tempting things especially on a new car, but you have problems with this car, fix them FIRST, otherwise you may be dumping money into a car for no reason, the car may not be worth fixing if it needs major work.

boost4age

Maintenance is all i really been doing. i feel like its at a point to where i make it how i would like it to be or get rid of it. I read in other threads that our engines have a issue with bad seals? Or something that is causing these engines to burn oil?

boost4age

it has about 128,000 on the clock

ECM burn outs are not a dealer generated myth. There are a few very reputable Maxima ECU rebuilders for that very reason, and I've dealt with my own ECU woes. Search ECU and you'll find several threads with photos of burned out Mosfet drivers.

wut type of leds did u used 4 the climate contro

boost4age

Are you saying that i should get it rebuilt instead getting a new one?

mrpopo573

Pull your ECU and visually inspect it. What trouble codes do you have? Your pre cats could be causing any and all power/driveability issues you have.

See this thread for ECU photos:

I agree with what you said as far as the fixing the major issues(oil burning) if they can be fixed....before dealing with interior

boost4age

the odd thing is there are codes but related to the pre-cat and something else that i cant re-call right now. But i didnt see anything related to the ecu, how could the pre-cat cause those issues? trying to accelerate and it idles out and the abs light comes on?

mrpopo573

Do you have gas mileage and power problems? What do you mean by "idle out." An ABS light should be just for an ABS problem. Get the codes written down.

boost4age

when i say idle out i mean like i'm driving and i try and step on the gas the tachometer drops to 0 and the car wont rev. it will roll to a complete stop with the abs light on. From what i was told and read on this site that would be an ecm problem.

boost4age

I know for sure that one of the codes were p420 Catalyst system efficiency

mrpopo573

So the car dies, right? I would change the IACV and do the idle relearn. But it sounds like you might need a mechanics opinion if you feel overwhelmed.

boost4age

Did that already they put me on to the idea that it could be the ecu so i came to the forums to see but then you mention that the pre-cat could be the problem. I saw this being discussed before about clogged pre-cats causing engines to die....i did a google search and found this http://www.nissanforums.com/qg18-1-8...ml#post1289145

i wondering if its possible to run the engine with that pre-cat off to see if it runs how it should....but if its clogged it should be obvious right?

mrpopo573

This is beyond me, as to whether you can run without it. I believe you can't, and that the engine needs that o2 sensor reading downstream for correct operation. I defer to another more experienced member on here. Someone will know.

+1 million - You can go from running fine to barely running/blown engine in literally no time flat. You don't **** with precats (or main cat for that matter). Gut em or headers.

Bad rings or not, I bet you're burning most of that oil b/c of the immense back pressure of clogged cats.

Child_uv_KoRn

It won't need it until the engine is warm and even then I bet it goes back to a default type map if neither primary is working.

boost4age

whoa didnt expect that but it does make sense ill start by taking a look at it to see what type of condition its in. How would you gut them or what would you use to gut them? i know sometype of non-fouler would be used on the sensors right?

Child_uv_KoRn

iTrader: (7)

You have to take the manifolds completely off. Most people just opt for headers

million threads on this btw

Your in Florida, typical warm weather so to gut em you can just drop the y-pipe and gut the rear without taking off the manifold or the precat just got to have a long screw driver or pry bar to break it all up and out, and for the front just take off the precat and do the same. On the oil burning issue mine was about the same and crapped out at 153k, put a 04 engine in there and no more oil burning issue....SOONER OR LATER you will need a engine, better you get it sooner, and you will find one used and cheaper than repairing the one you have now...... Good Luck....

boost4age

Ill give that gutting the cats a try next week ....how much did it cost you to swap out your engine? if the oil burning problem doesnt go away after all this then i might have to go that route

Like 500 labor, 80 bucks for fluids, engine 800 total was like 1388, you got some people in Florida who does that on this Forum, don't know how much they charge but usually be in the Ghustle thread on the 1st page all the time, with like 40,000 plus post....

wow thats not bad at all. I will look into that after knock out all the precat things.

Include me in that. This has ruined my night.
On the other hand look out for mid july I'll be throwing these projectors into my high beams on the max

Next to a mini h1 projector

I should probably make a thread on this but I'll do it after I get it done :P

Ummm.. this whole thread is from the Thread Title. If you want to keep a well constructed thread that stays on topic and holds useful information and conversing, then you need to spend a couple seconds and construct it correctly in the first place. Don't get upset at us for following your lead. :P



Oh man Oh man, that's what I was hoping to hear when I popped in here! Get on that Greg can't wait for the thread, would be interested in a progress thread on it while you're working away.
