vehicles controlled by multi-electronic sensors are not my forte, even though I am qualified in Electronics, but I know dud sensors can cause weird problems.
have u double checked the integrity of all vacuum hoses?

Yeah I agree, and I checked every single hose besides every single vacuum hose. Took off what I could to have a closer look and cleaned everything. Have also got the WD40 out a few times, under idle or with higher revs spray the sh#t out of everything to see if revs go up or down indicating a vacuum leak, none found as yet. The only leak is an exhaust leak around the headers/extractors, but only very marginal and has been there the day I bought it (2 years ago).
I also cleaned the throttle body, pulled the 2 sensors cleaned them but made no difference, but I did replace the IAC 12 months ago, and have replacements coming for the other 2 sensors.
I still have my money on a sensor of some sort playing up, when its cold it plays up real bad, warms up and makes better contact or operation is better, plugs can still be the culprit and also the same for the O2 sensor. I think the plugs will be in tomorrow, so besides a new fuel filter, new plugs should go in as well.
Will post my findings.
