Hi guys havent been here for a while but i have no one else to turn too lol.
I'm having a lot of trouble with my engine, this is what happens;
-rough idling when cold
-hunting/surging
-loss of power
-blows smoke when it does it
-weirdly doesnt play up all the time, only sometimes
-will stall the engine

i know its an electrical fault otherwise it would do it all the time. i just replaced the spark plugs, leads, throttle position sensor, o2 sensors.

thanks guys...

first thing i would do is check for codes and go from there

Check clean maf..Coolant sensor ...
Check leaky diaphram in fuel reg.....
Check all connections on battery especially earth connections chassis to motor....
Check TPS voltage.. It should be under 1volt at idle and over 4.5v wot.....

Yesterday i turned the idle up to 800rpm and it doesnt stall now or splutter and stuff. but it still is hunting sometimes...

i had something the same look at your harmonic blancer mine was bent (they get that way after a few k's) i replaced it and it fixed it just a thought

another place to look might be the auto trans mine was rooted and had similar problems with the engine. Overdrive was locked on electranically causing the ecu to dump heaps of feul into the engine at all times
