C5 X7 163HP 2010 Tourer
This part (vacuum solenoid) from Throttle control manifold
was unattached (because it easily can come off), for some time, so my throttle flap did not move correctly... During that time I had an error P2141 (Exhaust system faulty), but nothing more, and no problems during driving...
When I discovered, and reattached it, some problems started... During longer trips, 200km or more, when become hot... vacuum started to close throttle (readings on Torque app via bluetooth) were 11,5% Throttle, and vacuum - 8 bar or more...and engine start to suffocate, and can not go over 80-85 km/h, but very slowly accelerating...
I will attach some printscreen photos from that period, and finaly, I disconected vacuum tube from Throttle, and closed the tube. Left Solenoid to hold threottle flap in possition, and it stays arround 83%...during faster rides it goes even over 86,5%, but dont go under 83%. Car now go nice, and no MIL light (before that I also had P0488 and P0487 error - Throttle manifold intake problems).
Can someone explain what is going on here...?
Before, normal readings: | Before, vacuum closing throttle (choking): |
Mix...one from before, and rest from now: |
Thanks in advance
