Welcome Visitor! Please take a few seconds and 99 ford ranger 4.0 v6 auto Any advice to find out where to look or how to fix this? I know i have a problem, whenever i come to a stop the engine drops low in rpms to almost stall state. The truck runs fine when driving/starting, only when at normal temps. The obd2 says lean bank 1 lean bank 2. Any advise would help.
