Ok so I took the pin out of the MAFS But before i unplugged my MAFS I tried to start my car and it fired right up almost stalled after about 5-10 seconds. Should i take it for a drive and see what goes on or should i unplug the sensor and do that or what???
It was the left one on passenger side but im going to unplug my MAFS now ill let you guys know what happens
There's simple test to check your CMPS and few other vital parts: remove it from the engine but keep the harness connected. Put ignition to ON and turning its shaft by hand - LISTEN. You should hear injectors clicking while turning the shaft. If you remove a coil and put a spare spark plug in and put it somwhere to touch the engine ground you can also watch the sparks while turning the shaft. ECU trusts this sensor a lot . It is a little tricky to put back, please be patient, it is not that bad: you have to turn its shaft to match the camshaft, don't force it in.

Hmmm..Bad connection maybe? lol j/k
TEST:
Try unplugging first..(engine will not rev over 2000rpm with it unplugged) see if it will idle/rev ok with it unplugged(trying to diagnose a bad maf here)
If idle/rev ok with unplugged, shut car off, plug back in, restart,let us know...Check the maf connector for corrosion and/or loose connection first!!
OK so i unplugged it and it revved to 2500 rpm no higher. I didnt try to start it after that cause i dont want to cause anymore problems but i have no idea??

good idea. but remember to make paint marks on the sensor and on the engine so you line it up the same as the way you took it off..... you don't want to mess up your base timing by lining it up wrong.

when the maf is unplugged, it will not rev past 2500. that's normal.

DO NOT PM ME ABOUT PROBLEMS WITH YOUR CAR UNLESS I TELL YOU TO. THAT'S WHAT THE FORUM IS FOR
I just started it again but i had to give it some gas before it started again. Once warm It idled at 1200-1300 rpm??? How do i post a video so you guys can see whats going on??
Im pretty sure i forgot to hold the clutch down after it fired up. It confused me and i dont know whats going on here
it fired up without holding clutch? is that wut u meant?.....if that so then ur safety switch is messed up....and how about the maf? after u plugged in, did it start?

that won't cause the car to stall out while driving!
he was flustered and accidentally let off the clutch with the car in gear, and stalled it sitting in his driveway, while trying to see if unplugging the maf would help. READING>>>>>>>>>>>> you

running the engine with the maf unplugged will not hurt anything..No rev past 2500rpm is normal with the maf unplugged...

You need to do the maf testing procedure exactly like i outlined in post #124, We cannot help you diagnose and fix the problem unless you do the tests and report back the results..calm down, relax, read, test, report back..
OK i unplugged the MAFS and it fired right up. This is weird because after i got home the car wouldnt start. But anyway with the MAFS unplugged it idled fine but wouldnt rev over 2500 rpms. Whats the next thing i should be looking for??
OK so you want me to unplug the MAFS and then what would you like me to do after i start the car??

Ok, now plug the maf harness back in, make sure the connection is not loose, start car....If it has problems running after plugging the maf back, then you need to replace the maf sensor.
Ok im gonna start by saying WTF. After doing these things things i took it for a drive and she ran like a beauty?? Im really confused but im not complaining. It didnt have the problems at all?? Its about 10-15 degrees warmer outside maybe my maxima doesnt like the cold weather it didnt start happening untill it was cold outside. Ill keep you guys updated. All of your help was greatly appricated! Thanks guys!!

sounds like you had a bad connection at the maf harness, just fiddling with it restored the connection back to good.
Let us know if you have anymore trouble with this issue, good luck..

Oh, that ... There's a spray called Deoxit which works from my experience. I recently got some gremlins myself - car started to act so strange when shifting gears (auto) that I started to worry if I would be able to get home by myself. Opened the hood pulled all the important sensor connectors, sprayed with that thing and put electrical grease in the connectors - 40 minutes later everything was back to normal and it's has been staying this way for a month already. I didn't even bother to pinpoint which one was actually at fault. The car shifted harsh like it does when you remove resistor but it also was doing 'double shift' when going 1->2, it felt like it engaged-disengaged-engaged again detween 1 and 2 and also didn't want to upshift to 3 and 4 easily. I didn't even bother to think much with all that went wrong at once.

you can flood a fuel injected motor. That is why you have the hold the pedal to the floor shut off the injector feature.
No, you cant brian, unless their is a mechanical problem causing the flooding, you can press the gas pedal all day long on fuel injected engine with the ignition on or off and it will never flood the engine out, unlike a Carbureted engine.

he meant cranking the engine over a whole bunch (which does simultaneous injection... lots of fuel for startup) and having a problem keep it from starting. if you then quickly fix that problem (for example, forgot to plug a harness back in that was needed for you to make spark) and go back to start it, all that no-spark cranking will have put a lot of gas into the cylinders... hence why you floor the pedal to start it in that condition, cuz you already have gas a-plenty in the cylinders.
******************************
as for the problem itself with this dude's car.....
he's checked all the harness connectors..... but what about grounds?

Well, i have been in here for a while since i bought a newer car, anyway, i was having a almost identical problem he is having, once in a while the car will stall wile driving, post a message here trying to find an answer, not much responded back then, started looking around under the hood and found out the battery terminal was crack, don't remember which one, replace it, never happen again.
It will only take a second, go check the terminal.

u can take that rubber cover off from the maf harness and pull the each wire going to the maf and u will find ur lose connection....i had the same problem and i jus went to the JY and cut the maf harness from GXE ( i have VE ) and hooked it up..since then never got any problems.....i hope dat helps bud....gud luck...
Sorry guys i havent been on in a couple days. But my maxima is still acting up. Im gonna check out the terminals and check out that MAFS plug. Ill let you guys know if i find anything different. Again thanks for all the help. Oh and if anybody has a diagram where all the ground wires are please post it.

Unplug the maf again, actually drive the car for a while with the maf unplugged(yes, 2500rpm will be your redline with it unplugged, this is normal, it's called "limp home mode") just ease the car around, don't hit the 2500rpm if at all possible..
If the car doesn't "act up" during this test, then you have narrowed it down to either the maf harness not getting a good connection, or a bad maf.
Ok so i unplugged the MAFS and it didnt help. It still had the problems. I dont know what to do anymore. Do you have anymore suggestions to do or look for?? I wasnt able to hit 2nd gear before it acted up (I was pushing on the gas pedal and all of the sudden nothing and then it came back and happened again and again.) The tachometer actually works while this is happening also. It must have just dropped to zero when it was stalling or almost stalled. Any help would be great??

Are you keeping the rpm of the engine under 2500rpm while driving around with the maf unplugged?
. It is a little tricky to put back, please be patient, it is not that bad: you have to turn its shaft to match the camshaft, don't force it in.
lol j/k
