Its definately it, you might have not installed the popcharger properly, causing the car to dump heaps of fuel therefore stalling your engine.

Hey this happend on one of my friends cars after he installed his intake, check all of your fittings and make sure they are correct. Right behind his MAF sensor the connection between his maf and tubing was off a little bit causing not enough gas to get there and it die out. Maybe this will help hope

seems like everyone i've seen post about this problem, and there have been tons of them (use search function; you have over 200 posts) had it happen while driving in neutral at freeway speeds. who tf does that? where did you learn to drive like that? it must be related to the recent poll about the average age of the z driver.

As far as failing a driving test in Holland goes, I'm happy for you. Congratulations on being European and more enlightened than all us dirty Americans. Before you get to comfy in your high throne, though, the past tense of "teach" is "taught," not "teached."
So why don't we all just move past this coasting vs. running through the gears thing? I dunno...maybe get back to this guy's question.
And what is my opinion on this guy's problem? Reset the ECU and you shouldn't have this problem again.

The poster you are mocking is from Holland where they speak Dutch.He's got pretty good English considering its his second laguage.A little grammatical error compared to a pretty stupid one while driving at speed seems to annoy you more? Weird!

Hmmm, Navygold thanks for teaching stupid foreigner correct English, but I bet my Dutch is better than yours.
My friend from Scotland thanks for your support.
The sudden drop of intake vacuum when shifting to neutral will cause engine stall. The MAF sensor is calibrated to determine the airflow in the inlet routing before the throttle valve. A closed airbox (the standard one) will create MORE airspeed at low rpm (idling) than the open pop-charger.
MAF sensor detecting value is programmed in combination of RPM, throttle valve opening etc. Recalibration the MAF sensor is the basic solution.

Why didn't you post this first? What made you feel the need to tell him and others that coasting in neutral was bad and that they would fail a driving test in Europe for doing so?
Anyway,as said any many prior threads the ECU doesn't like coasting in neutral at any great speeds, so guess what? Don't do it, end of story!!
Anyone who wanted fuel economy shouldn't have bought a 3.5L engined car
in the first place
Can we get back to a snuggly global forum now? please?

k i checked the connections and they looked good. I am disconnecting the neg battery cable for an hour before work to see if they resets the ecu and solves the problem

yea, I am going to try to coast on the way home tonight on the exit of the parkway again and see if it happens again. I disconnected the neg battery cable for about an hour. if this didn't reset the ecu, what's the other way to reset the ecu?

after unplugging the neg battery cable for an hour I thought the ecu was reset bc my tripometer read 0 and my radio stations were lost. but on my way home I went up to 70mph then coasted (stick in N) and the car still shut off. maybe I didn't reset the ecu properly? maybe there's no solution for this problem?

My god man, don't coast in neutral at 70 mph. Not only do you increase the amount of time it takes to stop (you aren't engine braking), but also if you have to do an emergency manuever valuable seconds are wasted bringing the car's RPMs back up to speed, plus you have to shift and all that jazz. Additionally, you aren't saving any gas by putting the car in neutral, just coast in gear and let off the gas. When you do that the car's wheels are turning the engine, and the fuel injectors turn off, or damn close to off. If you are just coasting around in Neutral, the fuel is turning the engine at whatever the idle RPM is.
