Hi and thanks again!
That was good advice to do and i did it.
So results i got was, heres a list again:P
1. Without pressing gas tps was 17% as at iddle it is 13-14%. Maybe normal as its not running but sometimes without touching anything it climbed to 18 and 19%
2. I felt little that when i tried to press the pedal very linearry tps reading did not rise linearry it went like it took a little break and then fast up few % and so on. But it wasn so noticeable as its hard to press with foot so sensitively and linearry:P
3. Tps reading at WOT was in highest 86% and that i know is normally from other Minis too but it didn always get so high in wot and sometimes it was 83% 84% and 85%
4. But the last one was interestin to see as i pressed pedal slowly down and tps reading arised until it stopped and even i pressed more it dropped to this 19%. Mostly this stucking happened around 50% and then when it dropped to 19 it didn change anymore even pressing pedal.
And once it got stuck in 21% and once at 32%. Switching power of and back on made it go back to 17% and moving again until it again stopped and dropped to 19%
So based on this i came in this conclusion in my little brains that surely there is something wrong in either tb or tps and i don think there is any doubt on that.
Basically again in my little brains i thought that either it could be that some fault in TB makes it to close itself or faulty TPS makes it think that its closed as i think that either thing would get these cut outs happen while driving.
Not sure how exactly TB works but if its like that the motor opens and spring closes then maybe it could be somethin like no signal and spring closes it or i could also think that if u try to press pedal and it mechanically stucks computer would stop giving signal to it to prevent any damages that might occur in the situation and again it closes then
Then i also started to think that could maybe bad signal from the pedal cause this? As earlier on summer it was on mechanic cause of carbon buildup and they said that pedal potentiometers had some little variations. At this time it was anyway left like it was cause i found that those problems was caused by this buildup and valve cleaning cured that. But now i am thinking that maybe those problems then was cause of buildup and this new thing and now its just getting worse.
Again I think that first I could check from my parents citroen C5 how its tps behave as it has same engine.
And after that i could take the TB of and just see how it moves when using pedal and check what kind of results that gives.
And yes also this that some minis have had problems that throttle gets ice and get stuck cause of that and those had just the same behaviour with the revving up and down
Oh my again so looonngg post:P
