VDC and Slip Light problem = no acceleration

[ericr33914]

I went to get an oil change last night and when I left the "service engine soon" light came on. I thought nothing of it and figured it was just because I got the oil changed and I would just have my friend clear the code when he gets back later the next day when he gets home.

I drove around for a little bit and then later last night when I was about a half mile from my house my VDC and Slip lights came on and my car stopped wanting to accelerate. I tried to hit the VDC button and it would not turn off, nor would my car rev up if it was in neutral. I managed to slowly get home at like 20mph and tried to turn the car off and reset it. When i turned it back on the lights came immediately back on and the car still would not rev up. You could floor it and it will very very slowly go up to about 2k rpm and that is about it.

I turned off the car and let it sit for about 5-10 minutes, came back outside and started it again and it was fine. I brushed it off and tried to think nothing of it and hoped it would work on the way to work in the morning.

So I am driving to work this morning, which is about a 40min drive and it is fine until I get about a mile away and it happens again. I had to drive the rest of the way at 30mph and without stopping since I could not accelerate. I am really lost as to what is going on and would appreciate some help so that I can get home this evening after work, thanks!

Check your brake fluid, apparently they go crazy when it gets low. If that's not it go to autozone and ask them to pull the code for you. They'll do it for free and that will at least point you in the right direction.

[03scgt]

your car isn't happy about the spray.it threw the codes to protect itself.stop trying to rev it and take it to get the codes read

[Semi Jew]

yeah. check engine = no going fast.

get that shit checked, make sure that the right amount of oil is in the car too.

[STiDriven]

Drivetrain issue? Maybe your diff is heating up or something causeing it to go into limp mode.

[ericr33914]

the thing is I havnt even raced it or had the bottle on it for about 4 days, it has been driven to work and that is about it. It was perfectly fine until I got the oil change, and as soon as I got in the car to drive away the engine light came on so I would assume it has something to with the oil change. I probably should have had them check it but I figured it was no big deal because my malibu used to throw the engine light sometimes after an oil change and it was just the computer being dumb.

[03scgt]

nissan and any dealer related issue means your fucked

[ArsenutsJR]

MAF sensor is shit.

[03scgt]

MAF sensor is shit.

your right matt.I diddnt think about it but that explains all the problems.when we were messing with rons m3 that's what happened.


Try and unplug the maf while the cars running and if it doesn't die or idle bad it's the maf

[05Gtsprayed]

Ford has it on there cars to, its called
FailSafe Mode, has happened to me many of times check the Throttle body blades first, after that check to make sure everything is still where it should be Voltage could be where u tapped into your Throttle Control for the NOS system it fucked it up there and is cause a werid Voltage spike or drop. Thats happened to my car many of times, Atleast u got 30mph. I had no pick up just idle i had to go through all the girls baby slow to get my shit i waddle home, then after the 3,4,5,6 time i had it towed home.

[05Gtsprayed]

See Slow4DOOR what a little 75 shot can do to a car?

I tried taking the maf off while the car was running and its stuttered when i first took it off and then it idled fine. when i went to check the rpms though i noticed that taking the maf off caused the VDC and slip lights to come on again... hopefully they will go off again if I let it sit for a while.

If you got an oil change... left the place and your CEL was on.. I dont think I would have made it very far before turning around and getting them to fix it.

I would let them know that something is screwed up, but since you drove on it for so long and havent done anything... you may have waited too long.

edit: was this only an oil change or did they check/change any other fluids? Maybe a trans or diff fill bolt was left off.

[ericr33914]

Its my friends oil changing shop off of del prado, so there shouldnt be any issues with going back to him. All they did was put in some oil and i think they filled the washer fluid I couldn't tell.

[VTC_WS6]

Rahter than guessing... why not just get a generic code reader and just pull the codes so you KNOW what's going on?

I am going to do that tonight, i was just trying to see if I could figure something out so i didnt have to take the chance of it doing it to me on the way home from work tonight since I work in naples.

[michael350z]

Did they drop the under panal to change the filter? If they did they might have hit the o2 sensor wires, they have been known to come loose.
Slide under and check them.

[VTC_WS6]

If you work in Naples you could swing by the shop and I'll check it for you..

[05Gtsprayed]

Watch out most place's wont check it at night like AUTOZONE and DiSCOUNT they say its not safe i think there just lazy

[ericr33914]

I took it to get the codes read and I had a MAF and 2 TPS codes. I am assuming that the maf would cause the TPS problems?

[VTC_WS6]

Or a bad throttle body..

[Kevin]

Have you fucked with your throttle body lately? Cleaned it...etc?

[ericr33914]

Nope.

[Hawk]

did you wire in the WOT switch in for the N20? I would start there, then work towards anything that couldve been bumped during the oil change.

i would check this seeing as he also owns a 350.....

[ericr33914]

I checked the codes again today and now I have an ECU code too. The maf code isnt showing up anymore its just the 2 tps codes and the ecu. The code numbers are: P0222 Throttle Position Sensor, P2135 Throttle Position Sensor, and P0605 ECM/ECU / machine said "P0605 Internal Control Module Read Only Memory (ROM) Error". We tried to clear the codes again and now they wont even erase and the car seems to be in permanent limp mode. Also, not that its really a big deal but when i turn my car on now my dvd for the navigation is going crazy trying to read shit when the nav isnt even on.

[ArsenutsJR]

I would either say faulty sensors or If you are spraying its a possibility you fucked you ecu by making it read and run while on spray. Now that there's no spray the computer cant read it. I doubt it has anything to do with the navi. That's prob. just another problem occurring at the same time.

[03scgt]

like i said before dont spray a car without a tune.but what was your answer "their good for a ____ shot without a tune".pull the srpay off and take it to the dealer,hopefully they wont find out you sprayed it but most likely they will

[michael350z]

Did you do an ecu reset?
It would not hurt to try it.
Just disconnect the battery and step on the brake a few times to get rid of all charges.
Then let it sit for awhile and reconnect. It's worth a shot.

Well no one else on the forums had ever had a problem with it and I haven't even sprayed my car in a while. Also, it shouldn't matter if the dealer sees that I have nitrous, I don't have a warranty anyways.

I tried that and it didnt work. I also tried the manual ecu reset where they tell you to turn the ignition on, and step on the pedal with different combinations... and I could not get that to work either. The check engine light is supposed to flash and I cant get it to do that, I tried it like 10 times. We can't get the codes to clear with the code reader either now.

[03scgt]

I diddnt know you diddnt have a warranty.you spraying before the maf or after?

[ericr33914]

after, spraying before would be pretty dumb

[03scgt]

I know this.just seeing if you did it

[05Gtsprayed]

Look at my first thread i told everyone the throttle postion Senors is the fuck up. If those blades are reading wrong then the whole car goes WTF take off your throttle body and reconnect it from there.


MAybe Next week we can be hearing the same story from SLOW4DOOR

[trans99am]

whats wrong with spraying before the maf?

and make sure you tell us what the problem is when you get it figured out

[ericr33914]

because then the nitrous hits the maf which is no good for the maf.

[whitecord]

my guess would be check the wire to the tps. if you have a nitrous kit you most likely taped into those wires. second disconnect the negitive treminal for 15 min. that should reset everything including your learned values. if the faults wont clear that means the fault is still present.

i think you said be for you checked the forums and no one has had this problem b4! thats why it sounds like user error in the wiring to me. take that shit out and make sure none of the wiring is shorting. and if the fault is still present you will need to get a tps or throttle housing if it is not replaceable.

[trans99am]

I have heard of alot of people spraying before the maf so that the maf picks up the extra air and forces more fuel?

[ericr33914]

there was a problem with a wire going to the throttle body... its fixed now.:D

[whitecord]

your welcome...jk

[05Gtsprayed]

Fucker next time listen to me. LOL i have been in your shoes with the same fucking problems.
