Our Ol cars sure do like to try us !!!,,,for a While now,I'd Suspected a bit of Dodgy Wiring,The 5 Wires On the AFM Plug,although I now run Map Sensor and AIT,as I have the AEM Standalone,,I'd simply had Them Piggy backed a couple of inches Back from the Plug,,so I could Revert back to Standard ECU and AFM,should I need to.

Anyway,the last week it suddenly got worse,,,to the point the Engine cut out when i Wiggled the Wiring !!,,so I set about Finding the offending damaged wire,and Swapping in a New piece,,,but it was so Hard to pinpoint which Wire was Messing about !!!,,,Now With the 5 original wires attached to the AFM Plug,,,there's now another 5 piggy backed on,a possibility of 10 !!!,,But just when I thought I'd got the Culprit,,it wouldn't Cut out when wiggled,,and I'd move on !!,,,!!!!,,and so I ended up painstakingly replacing em One by one !!,and found it to be the larger blue Wire from the Map Sensor,and the green with stripe wire it piggy backs onto,,once They were Replaced,it was happy days !!!!!

There's still that hesitancy if I plant my foot from standstill,,but I read somewhere that it is a bit of a trait of the supra,and With the AEM ems,,some guys have used the HKS twins park system,to improve that
