FD Juddering/Power loss
Hey guys,
Just wanted to put something out there.
I have a 92 FD3s with Apexy Power FC - It recently had the AIK sensor replaced due to a fault with the original. The fault is now cleared according to the commander. When i got the car back it was running perfect, was very pleased.
However only a few days later taking it out on the track. I first noticed that when i tried to accelerate from 60 up to 100mph it starts to judder looking at the commander the only thing i see strange is the injector % it won’t go past 43%.
The other symptom I have is that it sometimes idles between 1100 and 1200 as if the Apexi unit was learning. This doesn’t happen all the time.
Also the Heat light has gone from flickering to always on. Now I am thinking I have injector problems or 2 the ecu is cutting power back due to some fault.
Anyone’s help much appreciated.
Mods;
Apexi running base map
decat and aftermarket backbox
hks sequential BOV
Standard/original for the rest of the car.
