Im driving down the freeway. get off at my exit (to go to an evo meet of all places) and then. my car just dies... i start it up and it hesitates a little... then starts up, so i just manually hold up the revs at like 2k so it doesnt die till i get to the meet. then i park, and psh dies again. im like oh noes must be a intercooler piping or something. i check them all and they are fine (when i drove home it boost's just fine)

so, what could this be? a couple friends told me it could be the following: Fuel pump? (i have a walboro), Vaccumme lines (i checked as many as i could see when i got home) and someone said it could be an intake issue...

now since it boosts fine, and drives good just until i let off the gas, it doesnt want to idle and just dies...

by the way, the evo meet didnt help much becuase 3 of my friends that might know something about it were completely hammerd and were giving me stupid *** answers like: "must be the flux capacitor" "your hid fluid must be running low" so then i just left


EDIT: so far as of now i have replaced the:
Spark Plugs
Intake
MAF
Fuel Pump
PCV valve
Coil Packs
Blow off valve
Turbo

scanned the cell and got P0102 Mas or Volume air flow cuircuit low imput..

 

I agree with the flux capacitor answer.

It sounds like something to either do with the IC piping, or the intake itself. Follow the intake tubing and see if it's still on the turbo.

 

turbo intake.. it sounds exactly like the issue I had some time ago.. and hoping you aren't VTA as well...

 

not VTA. and i checked the intake like 10 times... thats not it.. any other ideas?

 

how many miles on your car?

 

idle air control valve may be dirty? thats what happened to my mustang . had to spray carb cleaner into it and everything was perfect after that

 

If you have a few miles check the PCV valve.

Otherwise make sure the MAF connector didn't come loose and make sure that all of the pipes after your intake pipe are tight.

Does the car boost ok IE is it ONLY an idle issue?

 

car has 71k miles

boosts fine. only the indle issue...

NEW INFO: try'd to start her right now, and white smoke was comming out the back? could it be a fuel issue? ill check the PCV valve

 

changed the MAF censor and the intake filter, along with the PCV Valve

car still wont idle. just dies.. also white smoke still comming out of the back

 

smoke...

all white smoke = water, could be from it being cold outside or a head gasket leaking...

blue tint white smoke = oil burning issue...

do u have any type of flash and have u changed ur plugs lately?

 

and also... wut were you doing that may have caused this.. hit fuel cut or antyhing like that onthe freeway?

 

are you running rich?

 

nothing out of the ordinary, just normal driving. i wanst even hitting boost that much..

alright just did the spark plugs... not smoking as much anymore...

so now, this is all that has been swapped: New plugs, New PCV valve, and a new friends maf censor.

so its still not idling and a little less white smoke.. but yeah. idk any other ideas?

 

hmm.....

What were you doing just before this happend?

Take off the oil cap and look down into the valve cover, also check the oil dip stick. Do you see a mayonaise like substance? I suggest a compression and leak down test of your cylinders also, especially if there if coolant in your oil.

One more thing, was there a lot of oil buildup in your intake, charge pipes ect.?

Change your oil and check itl to see if you have any water or coolant mixed in it... You may have lifted the head and blown the head gasket somehow... I'm just throwing it out there because thats how my idle issues started... Good luck.
