MAF sensor problem, ECU?

[mistaanime]

Aiite..so my car isnt running well at all...it's like the timing is off..but it shouldn't be because it wasn't haveing this probelm before..and after i changed the intake..all hell went loose. My maf connector broke..okai..so i got another MAF a new one from kregan..and it still did the same thing...changed the coolent temp sensor..nothing..changed spark plugs and wires..nothing...i checked the distributor but it seems clean..and fine...and then i finally came to it got a new maf..310..for a maf..anyways..after changing it..nothing..still sounding like shit..and if i still drive it..it stalls out..anyways im thinking it mite be the ecu..not too sure..but anything you guys? i took it to the shop and they told me its the maf..so i went and exchanged for another one..same deal..over my life time with the 91-93 240sx..i already went through 4 Mafs..and now im on my 5th one...oh and check engine lights shows that it's the MAF sensor that is going bad too..

maybe its the maf wiring. If any of those wires tough together all hell breaks loose. Check that out.

[mistaanime]

man..im thinkin it could be it..but i dunno how to check them..thanx tho

[mistaanime]

anything else???

you just need to ohm the wires from the maf connector to the ecu connector.

Get a FSM they to know the procedure.

test if continuity exist.. if everything is fine its not your wiring... cross check the wiring to be sure ( ohm wire 1 and 2 - 1 and 3 etc ) .. one time there was 2 wires for the ignitor that were shorting together ... took me 3 month to find out ..

good luck

i believe i am having the same problem, sept i have an sr, and i was drivin home one day and i have my maf wiring running through the front of the engine bay down to the intake and somehow the wiring came loose and got caught up in the alternator pulley belt and ripped some of it up, now it idles real weird like theres a vacuum leak and it stauls occasionaly just crusing, and i opened the wiring and looked theres 3 diff color wires the black one is tore up a little bit then theres a hole shit load of real real thing silver wires wrapping the other wires that got ripped up so i dunno how to go about fixing that, but yeah thats my story,

i had the same problem and thought it was my fuel pump and now i cant start the car
i'm thinking 3 things as of now dist' cap and maybe coil or wires if an anything maybe the injectors
but yeah man as soon as i changed my intake that happen to me too.
i cant stand this shit anymore!
does anyone have a chart on how to read codes and get reading from the computer

[mistaanime]

read the computer....the diagnositic?

[marios13]

yeah thats what im looking for but i got it you should try it too.
http://www.240sx.org/faq/index.html try this shit on the left and look for ecm dohc if thats what u have

[mistaanime]

haha...thanx..i got that..already..execpt..i still can't find the problem..cuz..i dun think it talks about how the wires that connect the maf
btw...good find.

[mistaanime]

any other thoughts about this situation?

[mistaanime]

bump.................

[mistaanime]

ok...nothing..i checked the wires..the white wire and black wire with grey line is recording 12.2 so..it's okay..and the Black wire im guessing the negative is at 0..anything else?

[mistaanime]

c'mon guys..any ideas? checked the Maf harness and it seems fine..what else could it be..i was thinkin Fuel Pump but not too sure..im going to last resort in getting another ECU

[mistaanime]

for those guys doin a search heres the answer...change the ecu
