Car seems to have all power but little rough idling.
Also on splited connecting tube only rhd side have vacuum, on lhd side there is no pressure. I changed vented duct on lhd but no change...
On carly i am getting throttle angle-manifold vacuum-corellation and charge air cooling-energy operation.
All problems started after season in garage without start and low battery warnings.
Please help someone

Anyone know the right solution for this problem? Passenger side vent line was leaking a little so I replaced it. That led to the car running rough/misfiring on idle. Runs okay once moving. If I disconnect the passenger side vent line and partially cover it so it’s leaking a little it starts to idle correctly again. Related to check valve in driver side filtered air duct?
