that same crossover goes nuclear. yep. thats a bad one, its called egr.
The same crud from the same egr eats plugs, dirties pistons, and retarding timing is retarding power after the dirty perma egr pings start, and that equals fuel consumption. Let the engine stay noisy until a longer warmup. its quite ok. A thing called reality. It might even have tapping valves...

Engine cleaner following instructions closely and the miracle goops for fuels does function it back to normal. At most, given normal miles, valve seals may need help from the same torture the egr gave everything else.

Cold air for fuel injecteds, being sure to have plastioc tubes where metal may hurt electronic meters. Carb version can do ANYTHING. play games with it or not...same results, unless fixing an extreme rarity (they all do)
