I'm having a problem with my car running rich. The exhaust fumes are horribly strong and I get a puff of smoke sometimes when I get on it, also when I'm driving my cars air/Fuel ratio usually runs in between 14.3 and 15.6, but when I am slowing down and the rpms are dropping the motor will start to bog and the air/Fuel ratio jumps up to 22.3 and stays there. I bought the car like this and can not figure it out. I thought it may have been the plugs or wires and changed them but it still does it. I have no check engine light either. The plugs were fouled out too when I changed them. Put new ones in and checked them a couple days later and they were the same way. If anyone could help me out I'd really appreciate it thanks.
