Rough idle after crossover pipe replacement in 2017 discovery
Replaced Crossover Pipe Now I’m getting P2187 and P2189 system too lean at idle codes with check engine light. Coolant system is repaired now with no issues, but truck is idling rough and jerks at acceleration around 1500 rpm’s. Any ideas? Thanks!
