Please help my car has been doing this since i bought it, 03 enthusiast, ill be going like 75+ and then if I throw it in neutral it will stall out in about 2 seconds, engine completly shuts off, not to mention that my car has been in 5 times for pulling to the right, 3 times for rattle, 1 time for tire feathering, window grease tsb, and wind noise in the driver window!!!! whats going on?!!?!? can someone assist me in whats the problem and what to do, thanks

 

Sounds like you might have a small vacuum leak. Open the hood, start the engine listen for any hissing/suction sounds around the plenum. You might have to take off the engine cover to do it though.

 

ya thats what the tech who did the test drive with me said, makes sense

 

Why would you put your car in neutral at 75MPH anyway?

 

I'm wondering the same thing^

 

I also have heard about some crank sensor that make the engine stall and sometimes shuts engine off. Check it out

 

Seeing how I never thru my Z into nuetral at 75 mph, maybe your car is just telling you to get out of the car cause you can't drive. Just kidding.

 

I've heard of this happening with people who have the JWT pop charger installed incorrectly. Do a search on this, I've seen threads about this before.

 

glad i never stalled at 140!!

 

yeah i think its related to the pop charger. check out some threads in the engine/FI section. people had stalling problems with injen also. People say they just reseted the ECU but unplugging the neg terminal and leaving it off for 24hrs. for some people it worked.. some didn't

 

Its called "blow back" and is from the JWT popcharger. You either have to drive your car without letting it rev down to fast after hitting high RPM's, get a SAFC feul managment piggy back computer to adjust for the blow back, or take the JWT popcharger off oyur car.
