This is kinda weird as it only happens sometimes. I have been driving my car for years and know that it runs well but recently hasnt. The problem is that sometimes the car smell really rich and when im driving around 2000-3000 rpm sometimes it gets jerky until i step on the gas then it runs normal. It only does tihs sometimes though. Also when I come to a stop sometimes the idle falls to around 600rpm and 10 on vac but othertimes its fine and pulles 20 vac at like 820 rpm. I did a boost leak test and didnt find any. Ive replaces the plugs and gapped them .028 but that wasnt it Any ideas? o2 sensor?
