Thats the outfit I have used before and they are very good generally.
As for the smoke, do check the obvious.....i.e. airfilter, fuel filter etc.
Almost There.......
Right, the smoke was mainly down to having too much oil in the engine, i removed to the max level (about a litre) and that seems to have stopped.
As for the lack of power, well, losing the excess oil has helped but it has identified that I'm not losing compression or electrical power but i seem to be losing fuel feed, just going to get a fuel filter and start from there.
It is running ok but if you put your foot down lets say on a nice long straight you can keep your foot down and the engine will stop revving for a about 3/4 secs and then carry on, and then repeat, asif its running out of fuel and then not, its not that noticeable at low speeds.
I would not be surprised if the filter is partially blocked, with this problem i have ran the tank empty 4/5 times and a month ago it had two treatments of Redex.
Will report back..
PS: The ECU repair place is not far from you Mark, it cost me £129.00 for a rebuild of my own ECU, but i did have a few administration issues , first of all i called to see if they had received my ECU and the quote i was originally given was upped to 180+vat which i took as maybe i had not heard them right in the first place, but when it came to paying it was in fact £108+£8 shipping+vat and for some reason they forgot to dispatch my ECU and that caused 2 days delay but apart from all that i was happy with the service especially the price and it has a 2 year warranty and the main thing is they have actually repaired it.
at least i know what's wrong now.
