So I tune today and tune went perfect car dumped at 509rwhp and 446hp. On the way home from the shop car drove perfect. After traveling for about 1hr and 30min car was running great. Getting near my exit I punched it in 2nd to feel a pull car pulled awesome but 5min after that car started stalling and it turned off on me.
I turn the car on and it starts up but idles for about 5 seconds then it shuts off, any idea why this is happening?
Most likely wouldn't allow it to start in the first place if it was spark plugs. Like I said, disconnect the MAF and try and start the car. Let me know what happens.
that's not gonna be spark plugs. Gotta be some sort of sensor. Did they put a chip in it? If so maybe they didn't clean off the pcm well enough where you connect the chip at, if there's still **** on there it could easily get "disconnected" randomly which would cause it to stall.
Kerm I'm going to try the MAF sensor and let you know but why would you think it's that? And no they didn't chip it he wrote the tune downloaded it to my diablo sport then downloaded it to the car
do you have the option of downloading a different tune back onto your car while saving the one he made you? that way you can try a different tune just to see if that could be it.
