No codes? wtf? I am trying to figure out what is the cause. Basically I will be driving and feeling horrid throttle reponse as if the car is dying but getting restarted backup because I am still in gear but once I shift or put it in neutral she will plummet but only sometimes. She died on my 4 times so far in the past week. It will go from 600-700 idle and then like try and try to keep it there, go up to 1.3k and then down to 200k and die. I had to start my car going 40 a few times. lol


Anyway, I am thinking it is either the maf, or IACV related. but the thing is, I just cleaned the IACV like in march. So I don't think it is that. The Maf could be it because I kinda broke the pins on it and jerry-rigged it to put it together and its been working fine for 6months. SO I unplugged it while running to test to see how the car reacts and of course the car dies instantly and throws a code about that. Yet, If it was the MAF I SHOULD be getting a code and I am not or any codes. Also if it was a bad MAF the car would die all the time and not run over 3k iirc, but it only starts running crappy or dying like maybe a few times a day.

O and car has no issues on the highway other then crappier pull.


Thoughts? Thanks. I really need to get this fixed Asap. I think its sucking my gas more.

i jerry-rigged my MAF one time and it worked for a few weeks and then car started to die sometimes. a really bad MAF would cause the car not to go over 2500RPM. i would say go to a local junk yard and get a MAF and see what happens, you can always return it if its not it.

check all hoses to your intake make sure no leaks also check your throttle positioning sensor.

IAC valve?

how old is your fuel filter?

you know I was thinking it might be fuel related, the fuel filter is olddd. lol

hmm which one should I get.... Maxima or 300zx like you guys do... haha

300zx TT fuel filter

ok, will do thanks Rocky... on my way. I think I will seafoam while I am at it.

had the same problem replaced the maf and runs great

ok, around 4pm today I changed the Fuel filter to a 96 300ZX TT and it seemed to do a little better with crappier throttle response. (i'd figure there is a small brake-in period.) After that it died once on going down a hill... odd? but was running fine after that and I went up to 6k a few times to get everything going all nice.

around 800pm. I was going up a hill into my complex and she started to sputter and die. And then it died and I couldn't even start it without hitting the gas.

So I think it may be an clogged injector or some issue relating the fuel because I would throw some code if it was a sensor right?

MAF or check the settings on your TPS. That might be shot

i would go with MAF but you definitely want to change that fuel filter also!

He already did.

Change the MAF. It may be giving faulty readings
