v35 V35 problem

[Versace1995]

I recently  changed my radiator  after it cracked, so getting to the point i put a need radiator  in and put new coolant  in and bleeded it then drove it to the carwash and washed it after taking it for a 15minute drive the car has a jumping feeling to it when driving and when slowing down it still has a high jumpy feeling does anyone know how i can fix the problem

Did you wet the engine ?

You might have wet the air flow sensor inside the air intake.
