I think Varche already has a spare gearbox ECU in Spain :-/

For those of us who haven't been paying attention could you give us a resume of what you have tried so far please?
When the symptoms include running fine at small throttle openings but dying when pushed harder you would usually start by looking for fuel starvation or blocked exhaust system.
Does it go into limp mode with the warning light on? or do you think it is doing it without showing a warning lamp & storing a code.
Six years ago when we used a caravan the car was gutless and nearly didn't make it up staxton Hill near scarborough. the local dealer diagnosed gearbox switch. After a new one it went better for a while and in fact we managed to tour Spain. However the car has never been zippy like a V6 should be. I have tried all sorts.
Check vacuum pipes. All as intact as can be ascertained. multiram operation I have managed to blip it so violently that I have seen the rear one operate.Breathers clean, no cam cover leaks, new plugs and leads. I need a new DIS pack as that just failed but have one in the post.
I have changed the fuel filter, Changed the cats, had a new exhaust system. During all of these things the performance has remained constant. It reminds me of driving an old car in too high a gear. The gearbox does change down but you have to really press the accelerator pedal hard on hills. Otherwise it changes gear fine on the level on light throttle (both up and down shifts)
It doesn't die on wider throttle opens so much as just being gutless. Possibly what you would get if the knock sensors weren't working. There are codes 21 73 and 135 but I assume they are to do with the current misfire problem which I am 99% certain is DIS pack. Last month there were no codes. the "limp mode" is just my interpretation. A little knowledge potentially being a dangerous thing!
Like I say I have lived with it for so long that generally it isn't a problem it just would be nice to fix it!
War and peace as Wellung666 would say.
