Hi everyone, first post and first time mustang owner, so far I love it....
So I got a ‘17 GT and started modding away lately, car came with Roush axle back and a H pipe that I don’t know what brand, but I installed the Roush cold air intake and got the RevX tuner through American muscle with the free tune from Bama...finally got my tune and told them to do it for the Roush with Venturi insert removed and 93 oct.
Uploaded to car and seems to run fine....except, when I start..especially cold start...the rpms sit around 1000 and then about 10 seconds later boom drops instantly to like 550-600 and it does there, idles smooth but such a quick harsh drop on a cold motor seemed weird...then past couple times I’ve driven I noticed when I’m leaving by the time I’m making into 3rd gear I look down the cars dead...the engine shut off...now I’m like maybe I slipped and hit the button (still getting used to such a awkward position for a start button) ....okay so next day leaving for work again about 3rd or 4th gear I go to slow down for stop sign and boom the engine off again...so now I’m like ok it’s not me...
It’s so weird cause it’s only happens so far in the morning when I start the car let it warm for a minute and start driving off to work... besides that it seems to be running fine and smooth but somethings not right...anyone experience something like that I’m thinking it’s the tune because since uploading it I haven’t run into this...
