parking or neutral die
 

so after a month of having my gryphon i noticed that everytime i put the truck in park or neutral the rpm goes really low and goes back up or most of the time it just dies.....

this happen to anyone else?


and my truck is a 2004 f150 5.4 xlt with 2 custom tunes 87 custom performance and 91 custom performance

Basic maintenance...........
Clean the tb.
Clean the MAF.
Replace the fuel filter.

If this doesn't help.
Then......
Set back to stock.
Disconnect battery.
Turn lights on.
Wait 10 minutes.
Turn lights off.
Reconnect battery.
Drive in stock tune for 50-100 miles.
Reload desired tune.
