I'm really at the end of my patience and tired of working in 4 deg temps on this thing. I'm sure you are right that I will kick myself when the mechanic tells me what a simpleton I am. But hey, if it is something small it means I might have a bit left in my wallet for a beer or two. As for smokes, I leave that to the mugs and enjoy watching them freezing their buts off in the cold rain outside after years of making my life hell in bars and clubs. Allright I'll get down off my soapbox now! Sorry, you may be a smoker.

I've pulled all the plug leads off and will hopefully match them up, or remake new leads if I can find the correct wire. I'm so focussed on the plenum/air leaks thing that I am blind to the actual problem. Strange thing is no matter what I do the symptoms have not really changed that much, except it is getting worse.

As for blowing the ecu, I have my doubts that it could be easily done. Its old generation electronics and really robust. Integrated circuits can't take much surge or stress, but resistors, diodes and transistors that the ECU mainly comprises can take a fair amount of abuse.
