When wires get wet wont auto shift wheel shakes (!)light goes on. Replaced spark plugs. ABS light on and off..

Hello, what wires are we speaking of? If you are getting the engine compartment wet for some reason (I never recommended "cleaning" the engine with water sprayed on it!), it's possible the ignition coils and related components could get contaminated by water and cause misfiring and all kinds of concerns. You mentioned it's after a car wash. But you'll have to clarify - what is getting washed? Yes, water can contaminate components and cause all kinds of concerns if this happens - have diagnostic testing performed with your engine performance and chassis components also (for the ABS light) to see what's going on. https://repairpal.com/auto-repair-near-me
