I think you have a loose or cracked vaccum hose. This happened on my APS TT kit. I found a very small crack in one of my vacuum lines and it would stall every once in a while, especially at idle after a quick throttle. Never on the highway though. You can get a vacuum guage to test all the different areas of the lines.

check them out.

 

Doesn't happen on mine. Hopefully you'll get a better response after SEMA.

 

any warranty on the work?

 

back in the early g35 TT/supercharger days, after one let off the throttle and the throttle body blade closed, the car would stall... this would happen wheather in park or while driving!

the easiest solution was to drill a small 1/8 inch hole into the throttle body blade, thus always allowing a small amount of metered air into the engine.

this also helped with people who had shaky idles...

i had to do this on my car with no ill-effects!

 

Well a car can die in gear and just roll to a dead stop, if it isn't get fuel or spark right?

 

Sam been very busy, I been waiting for Sam to hook me up with a TT for a good price. Well I think oreoleo got it right.

 

Same here! It's almost causing more problems than good.

 

I had the same problem a while back.

also sensors could be a culprit i.e. o2

 

Where you at in Texas? The kit comes with UPREV correct? They are the ones who made the tunes for GTM and they are only an hour from me here at Fort Hood Texas

 

im in dallas. where are they exactly? i might as well check them out

 

i dont think it be fuel or spark plugs. for all that was switched out at the shop. i really have no idea what the problem is. car runs great. just except this lil problem. like yesterday i was pulling out of the drive way and turned left. it died as i was turning going like 10-15. the other day it happen. my girl was in the car. and i told her my car died. and she didnt believe it till i had to fire it back up. so its happening quite often now.
i just want to beat my car with a bat right now. its frustrating.

 

Kinda sounds like the fuel pump is going out.

 

That's what I thought, Put a fuel pressure guage and run into your cabin and see if there is a drop in pressure, Also do a monitor of yoru car and see if there are any problems before dying.

 

Just to add, seeing as anything can be the culprit given the symptoms, check the cam position sensor. The random stalling reminds me a lot of my Maxima. For a few months there were no codes so nobody could tell what was wrong. Eventually, thankfully, an SES light finally came on.

Replaced the sensor and it's been running great since.

 

yeah im waiting for sam at gtm to send over the uprev cable and stuff over the email. after that then ill see if the problem goes on. its just been a month i been waiting for all this. its going on month number 2.
