Sorry for bump the old thread, but did you got the car fix ? What was the problem with your car ?

 

sorry to bump this thread guys,... I recently started having this similar problem. There is 235 k on the car. The car seems to start fine ...though it has become more difficult since I've been stalling. Ill be driving along, and all of a sudden the car just dies...the brake light, tcs lights all come on. My Service engine light has been on for awhile..took it in to my mechanic and he said the 02 sensor code came up, but this wouldn't cause the car to stall. I really have to press the gas for it to start up again. Im taking it back to my mechanic Friday morning.

From some of the reading I've been doing, ...sounds like it could be the alternator and possibly cleaning the throttle body and Mass Air Flow. Any other ideas?

Thanks for any help.

 

Could it be a FPR problem?

 

sorry I'm a beginner when it comes to cars. Whats FPR?

 

Fuel Pressure Regulator.

 

Okay, I have been having some technical difficulty so I hope this post makes it. I have been having similar issues with my 02 I35. I know this is the Maxima forum but this is what came up when I searched...my car has 170K miles and has been parked since August. Here's what I remember so far... January 2011 replaced alternator (1st time) car is okay until April 2012. While driving (60-70mph) car stalls and battery and brake lights flicker off and on. Car will regain power but it keeps doing this. Take it to have the codes read and it came up with O2 sensors. Had those replaced. Car still doesn't act right, stalls while driving, battery and brake lights flicker (Check engine light DOES NOT COME ON) Had the alternator replaced (this is still April '12) so we are now on alternator #2. Car seems great. Drove from Atlanta to Chicago and back no problems. Great gas mileage, etc... August 2012 car starts having issues again...Stalls while driving battery and brake lights flickering still (no check engine light)...
Go and buy new battery- starts up like a champ. Take my car to an "alternator" guy and he keeps it, runs it for a day (in the shop- doesn't take it driving) has the air and lights on and he says my alternator is working fine, proper output, volts, amps (whatever its supposed to be at-- it is doing). PIck my car up and on the way home...YUP...car starts acting up again. Battery and brake lights flickering. It didn't stall this time but I was too scared to drive very far. I have had the car parked since then as I didn't have the $$ to work on it. So- May 2013 I take it to the shop. They said it needs a new alternator... UMMM...hello...I think there is something else going on. They are honoring the alternator warranty so it's not going to cost but I'm skeptical, this will be alternator #3..I am not a car expert by any means and I am a woman and I know sometimes it's easy to think that I am over reacting, but I think that there is something making my alternator go out. I am having them replace the alternator but it just doesn't seem logical that I would go through the same issues. Why couldn't the alternator guy find a problem with my alternator? Why does it happen after being driven? I have been on all kinds of forums and have been reading...Is there something else I need to have them check? I've read about cam position sensor, ecu, mass air flow something or other, wiring harness issues, could be a wire issue after the alternator (not before), fuses...I just want it fixed...I just want to make sure I don't pick up my car and on the way home it messes up or either 2 mos down the road the problem presents itself again. (my shop is 55 miles away, btw)I know its common for remanuf alternators to be bad, but help a gal out!!
Thanks so much for reading my book- I look forward to hearing from ANYONE!!!

 

You are in the right to be upset about your situation. TYPICALLY when the battery light flashes and the car is stalling out you have a problem with the battery or alternator. I supsect that you are having more issues with your car than just your alt or battery if you have replaced them already. Yes you are correct in thinking that your cam positioning sensor or your MAF (mass air flow) sensor could be not working correctly. A common issue is for a MAF to be faulty and not throwing a code (IE the check engine light comes on). The problem with diagnosing sensors etc is that you have to change them on a "guess" that they are affecting your vehicle incorrectly. Most of the time unless you have a good mechanical understanding of your car and how things affect other things etc.... You are just guessing at that time. The thing with your MAF is that its going to be an expensive guess. Not to say that replacing your MAF anyways is a good idea, but it may not be the solution that you are looking for.

The end game of course is take it to the dealer, and have them diagnose your vehicle. Obviously thats going to cost a good amount of money to have them do it, but it might be the end of your problems.

I am going to GUESS that you are having problems failing sensors, bad grounds, or incorrectly installed or working parts. Just because people replace parts, doesnt mean they are in good working condition. I work at and auto repair shop and I see it all the time.

 

thanks so much for your reply...I'm thinking of asking them about the cam position sensor...my question about that is---if that is what is wrong with my car, would it cause the alternator and/or battery to die? If so, then I am about ready to ask them to change it...would that be a good idea?

 

Unplug that crap, its not making any horsepower for you.

This. I would get your alternator tested.

 

So the same thing would happen to my 02 maxima except mine would only do it once i had been driving it for a while. When it was cold it would start up perfect, but once it would warm up if I was driving it, the car would die. When I tried restarting it, it would take forever to start like 2-3 seconds instead of like normal 1 second. So I replaced the fuel pump along with the filter ran some lucas through the fuel system and thought it be perfect after that, (not exactly). About a week after I had replaced the pump it did the same symptoms, so I cleaned my MAF, NOTHING!!! So then I jumped on replacing the pugs, (PAIN IN THE ***) and now it works flawlessly. It gives me better MPG also!!!! hope this helps

 

Hi, i own an 2002 maxima and i am having the same exact issue that you went through.. can you please help me out i want to know please how you got this issue solved if by replacing the alternator or what?
