Car shuts off.....

BLK01SS · November 26th, 2008, 04:21 PM

Ok after I get done sparying the car like after I let out of the throttle the car will shut off. My buddy says his does this too but not every time. Mine does it every time. Any Ideas why this is.

what mods, who's Nytrous kit and where are the nozzle(s) located?

BLK01SS · November 26th, 2008, 04:31 PM

All of my mods are in "My Garage". The nozzles are located about 6" or so in front on the throttle body.

its in the tune. what shot size? is it tuned? who tuned it? whats your jetting? what plugs are you running?

BLK01SS · November 27th, 2008, 05:14 AM

I am running a 100 shot w/o a tune and tr6 plugs. Im not sure of the jetting I can tell tomorrow. It what ever the 100 shot is for nx

SWEET2KSTANG · November 27th, 2008, 11:54 AM

52/28?

when was the last time your fuel filter was replaced? a 100 shot can run untuned, i havent ever had an issue with mine shutting off.

i would check:
double check jetting
vacum lines and fittings
inlet fittings
clean maf
clean iac
change fuel filter (if needed)

Do you have an upgraded fuel pump?

SWEET2KSTANG · November 27th, 2008, 01:39 PM

no need for one for a 100 shot.

Given the tendency to lean spike from sucking the basket dry on the initial hit I'd say it's safe insurance

SWEET2KSTANG · November 27th, 2008, 02:06 PM

ot dont suck the basket dry. the fuel rails are at risk, but but not the basket. the lean spick is not from sucking anything dry anyways.

BLK01SS · November 28th, 2008, 01:55 AM

I have never replaced or cleaned the fuel filter, maf, or iac so I will look into that. I know the car will take a 100 shot untuned. And jets are n20:52 and Fuel:30. Thats what the kit said on that little chart.

mine has never shut off after spraying it....

BLK01SS · November 28th, 2008, 12:35 PM

just saying it has not whether it helps or not and I spay mine more then a little.

what plugs and gap are you running?

did you pull any timing with a tuner?

does it only do this after spraying it?

SWEET2KSTANG · November 28th, 2008, 02:46 PM

change that fuel filter first. and double check all you vacum lines.

BLK01SS · November 28th, 2008, 05:20 PM

Tr6 plugs gapped at .035.

No timing pulled b/c I don't have a tuner to do it w/ lol(Christmas).

And yes only after spraying is when it shuts off.

Yeah sometime this weekend or next week i will do that.

BTW its only if I let drop down to an idle, like after I let out I'll hit the clutch and let it go down to an idle but it just keeps goin and dies. But no if I leave it in gear it stays runnin I just like to let go down to idle after I let out.

SWEET2KSTANG · November 28th, 2008, 06:06 PM

that is usually either a sign of a vacum line leaking of lean issue. anytime the car goes from WOT (open loop) down to an idle, the car cuts fuel supply till it gets to desired rpm. if the fuel can not pick back up like it should, it will stay a little lean and can cause this issue.

BLK01SS · November 28th, 2008, 07:28 PM

Alright sweet we're narrowing it down. Any Idea where to start checking for a vacuum leak? Im gettin a tuner and a wideband for christmas so hopfully this will "help" solve any lean or rich conditions.

SWEET2KSTANG · November 28th, 2008, 10:35 PM

the lean condition is something that the ecu does, it is not feeding any fuel to motor since there is no demand when it is suppose to go down to idle. i would check the lines for the iac and pcv's. also check the lines to the plenum as well.
