New stuff -
Dorman 1 Piece Windshield Cowl
Quick Disconnect Negative Terminal Connector
Windshield Wipers

Passenger Door Upper moulding replaced (junkyard)
Custom DIY K&N Bracket Mount from a older mustang fitted to my system + (cut/drilled) + Painted

Painted -
Windshield Wiper holders
Painted Side Trim by driver/passenger door
Speedometer Trim (replaced from junkyard) + Painted
Center Radio Bezel Trim replaced (junkyard) + Painted
Last piece that was painted - Shifter Trim

ISSUES:
P0456 - Code keeps popping up sooooo I replaced the Vent Solenoid off a 04 Junkyard Mustang, seems to have possibly fixed my issue.

Car is running great, until after a certain time car seems to have RPM drop.

- Checked Short/Long trim readings

Car is Negative readings at idle and positive under load (2500 rpm) (LONGTRIM) Could be because of the evap leak but I think my injectors are the problem and my computer isn't adjusting to it quick enough. I will order a new set of injectors and go from there.

Currently no codes are present after changes and over 100 miles driven now but the car did stall once coming to a parking lot entrance(today). I was braking and turning in when it shut off.

August / October Update:

Oil/Filter Change: no metal shavings or anything to report
IAC cleaned again - new gasket
Coil Packs checked and tightened down
P0456 no longer came back
Newly rebuilt injectors
Passed inspection

Crankshaft Sensor replaced - The one on the car was for the 2011 CV motor. I purchased a Masterpro CSS for a mustang and now the car feels way better.

NVM THE CAR STILL STALLS !!

NO CODES THO

Happy Holidays!
