Update: Saturday 16th Jan 2010:
Items whcih were not done correctly by the first guy were sorted out. Using a wiring diagram - These were:
1. Idle Control Valve wired and serviced
2. Step-ups for AC/PS
3. Reversing the trigger points for the cooling fans (yes-these were hooked up wrongly).
^ The above "little" changes made quite a difference and now when the fans come on and the AC is on, the car no longer dies or mis-idles. There is no feedback going to the brain either which was happening before.
Timing is now holding and not being affected by when the fans come on which was literally sucking power - causing the engine to drop and thereby causing the ECU to ask "what the FU** is going on" and thereby retarding the timing significantly.
Oh...may i add, my Idle Control Valve was tampered with as when it was removed, the breathing space was about the size of an eraser on a lead pencil. Everything was clogged with silicone, black silicone may i add. All this gunk was removed and it started working like new.
However, a hard pull up the highway to home only resulted in the plugs being slightly tanned, nothing much to talk about. Plugs 1 and 4 were slightly coloured and t and 3 were white.
What's causing this ?
1. Wrong spark plugs ? - Im running brand new R7's
2. Set points for VVL ? - Im set at 4900 intake 5100 Exhaust
3. Injectors dirty ?
Question: I have some 370cc injectors which are bigger than the stock SR20ve injectors...If i slap these in would it necessarily mean more fuel ?
Those are the only aspect remaining to check again...
Will keep updates coming along...
For those of you wondering, im really not upset or annoyed or frustrated. This is a very good knowledgeable experience and i hope others reading can learn from this info and hence find solutions to their problems, if similar.
Much thanks to everyone especially Krack Korn who have contributed thus far.
