Figured out what's wrong with my car.
 

1. Knock Sensor
2. o2 sensor right front
3. EGR Control Solenied
4. Elecronic Fuel Injection

Gonna cost about $1000 to repair all of those, maybe cheaper but those are nissan's prices, I need to get them somewhere else that's cheaper.

www.jerryromenissan.com ($90 for KS) Easy to change yourself
EGR solenoid valve part #14956-31u10 (about $70)...easy to change yourself
www.oxygensensors.com

I had a little something similar wrong with my old 93 240sx, a couple fuel injectors needed to be replaced and a couple o2 sensors needed to be replaced to.....Nissan was asking $2300, so I sold it, bought a max...

How in Gods good name is it going to cost that much? I would get a second opinion on that fuel injection theory.

I'd do the first three and see if there is still a fuel injection problem...

Don't bother with the KS yet - the O2 sensor might be setting it off. Fix the other stuff and then check to see if you have a ghost code a week or two later :thumbsup:

Replace the O2 and EGR yourself. What's wrong with the fuel injection system? Go dump in some Chevron w/ Techron Fuel System cleaner in your gas tank or is it a fuel injector?

The KS code is being triggered by the O2 and EGR system errors. You most likely don't need it.

Put a new O2 sensor in it, clean out the EGR passages and clear the errors from your ECU. $90 bucks for the O2 and a few hours of labor to install it and clean your EGR system. Brings your $1000 quoted price down under $100 bucks and I bet your problems will be solved.

What code did you get that points you to "Electronic Fuel Injection"? And what are you fixing, replacing, repairing on the "Electronic Fuel Injection"? :gotme:

SO you finally bought a maxima, good to hear.

Thanks everyone, you dudes are great I will try to do this myself, I'll pic up the sensor over the weekend.

I took it to Nissan and got it tested (costed $100) and they told me the E.F.I and the others were the problem.

I'll pick up the repair book for the Maxima over the weekend, any instructions on changing the sensors?

And I just bought the egr for 60 bucks so I'll let you know how it goes :thumbsup:

This weekend I gotta replace the EGR solenoid and KS as well (KS is cracked in half :( ) also the Idle air control valve was literally fried, and clean as a whistle inside...210$ for the IAC valve :O

omg u could of just gone to autozone or advance and had them check for codes for free

ADVICE FOR ALL NEWBS: DEALERSHIP=STEALERSHIP. just wanted a price quote on the 97 temperature gauge cause i kinda need one so i called up and retailed over $100.
over $100 on a stupid gauge where ebay sells em for $1, well + $10 shippin

Scott, a little off topic.

Your screen name reminds me of an old rap group, Boogie Down Productions (if my memory is still intact).

Only 96 and up and I own a 95 max.

You can do it on a 95 also... My mechanic used it on mine when I first got the car

Or you can do it yourself for free... http://forums.maxima.org/showthread.php?t=104931

95s are ODBII also the port is on passenger side by the computer
