Thanks both for suggestions. Did not get to read them until just now - having boght a pump from a breaker on Ebay. Said it came off a 63,000 car so I bought it. It arrived this morning and feels tighter to turthan mine. Spent about 45 minutes replacing it and guess what - still hasn't cured the problem. When the engine is cold, I get no hesitation or flalt spot at all but as soon as the temp gauge shows warm, the flat spot comes back. What I can't understand is if it's a fuel starvation problem, why the engine pulls like a train when you get past the flat spot. i also noticed when I got back from the roadtest and banging my head against the bonnet, that the engine was lumpy at idle and low revs. I disconnected the FSV - following advice on a previous thread - and the lumpy idle became smooth. I then drove it with this still disconnected and the flat spot and hesitation has gone and the excess smoke too. Obviously, the MIL is on and there is also less power past 3,500 rpm. The FSV is brand new as this is what the fault code showed last week so can anyone explain this ?
Could just be that the FSV whilst new, is still faulty ?
How lumpy is the idle i.e very erratic and is it shown in the rev counter needle also maybe record some video and post it up so we can take a look.
Any signs of leakage from any of the injectors ?
Also have a read of this thread and some others of Ian's plight Sputnik comes back from the brink I don't particularly want to send you on a wild goose chase on this but it is more to point out whether there are similarities or not.
