Advice Please?...ecu Codes On A 300zx

[*ZxHuNnI*]

hI GUYS ITS ME AGAIN......

I POSTED A THREAD A COUPLE OF WEEKS AGO ASKING FOR HELP! AND IF ANYONE KNEW WHAT WAS WRONG WITH MY CAR....

TO GET STRAIGHT TO THE POINT.... I STILL DONT KNOW...

ALOT OF PEOPLE WERE TELLING ME TO CHECK THE ECU CODES.... AND AFTER FINDING OUT WHAT THE HELL THESE WERE I NOW HAVE...

tHE CODE THAT COMES UP IS "12" WHICH IS MASS AIR FLOW SENSOR. dOES THIS SOUND ABOUT RIGHT??

I HAVE BEEN DRIVING THE CAR FOR THE PAST COUPLE OF WEEKS WITH NO PROBLEMS.... IM SOO CONFUSED... SEEINGS JUST A COUPLE OF WEEKS AGO THE CAR WAS PRACTICALLY SHI**ING ITSELF...... REFER BELOW FOR DETAILS...

DOES ANYONE KNOW WHAT I CAN DO TO FIX THIS??

ARE THEESE CODES RELIABLE??? IF CODE 12 IS COMING UP DOES THAT MEAN THAT THE AFM IS STUFFED AND NEED TO GET A NEW ONE???

OR COULD THERE STILL BE SOMETHING ELSE WRONG WITH THE CAR?? BECAUSE I HAVE BEEN ABLE TO DRIVE IT AROUND FINE LATELY..

IT ONLY STUFFS UP WHEN IT WANTS TO.

IF ANYONE HAS ANY IDEAS OR CAN GIVE ME SOME ADVICE ON THE ECU CODES THAT WOULD BE GREAT

tHANKS

hERE IS MY PREVIOUS POST FOR REFERENCE:

Please Help Me!!! hI EVERYONE.....

JUST WONDERING IF ANYONE HAD ANY IDEA ABOUT WHAT IS WRONG WITH MY ZX?

I have no idea what the the problem is and neither does any mechanic i take it to....

Just recently when driving at about 100k's or less the car just started to lose power and gradually drop down the revs until it came to a stop......

Even when i put the foot down it goes no where... just jolts and gradually loses power, i struggled to get home. stopping and starting about 50 times.

But then a few days later i drove it it was fine! nothing wrong with it.

So then i took it to the mechanics and he said it sounded like the fuel fump was on its way out, so i had a new one fitted, and a service etc...

After this the car was fine again for a couple of weeks... i thought the problem was fixed,

Until last night the same thing happened again but much worse...

I was driving on the ballarat road when all of a sudden the car just started jolting and revving like crazy!

Then if i tried to accellerate it would jolt and lose power, until eventually it would just stall.

Then if i tried to start the car straight away it would start and then stall again.

When started at a standstill, the needle on the RPM meter fluctuates between the 2 and 3 really fast as if im putting my foot on and off the accellerator really fast but i didnt have my foot on the pedal...

Then if i try and take off the car really struggles... i have my foot on the pedal but it isn't going anywhere, just sometimes it kicks in and goes for a bit and then loses power.

However i have driven the car at other times with out a worry.

Does anyone have any idea what this could be?????

It cant be fuel pump or battery cos i just had new ones put in and a service..

If anyone knows or has the slightest idea please get back to me!!

Cheers

its probably your AFM(air flow meter).

It probably has dry/intermittent points on the circuit board. Resoldering all the points on the board can fix this.
