Jerking at high speeds.
So when I down shift and try to pass another car my car has started jerking while at those high speeds. I tested the TPS already and it seems fine. Where do I go next? Also I have the hot air on the drivers side cold air on the passenger side issue. I see a ton of posts but no real fixes any help on this would be great also.
Car is a 2001 Pontiac Bonneville SSEI
